Everything below concerns anti-doping. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-11-18. Where a claim depends on a specific study, the study is described rather than over-claimed.
Regulatory status varies by country and intended use. Major drug agencies have not granted marketing authorization for SR9009 as a medicine, and it is not listed as a controlled substance in many jurisdictions. It is often sold as a research chemical, a category that may fall outside pharmaceutical manufacturing rules. Buyers should verify local laws and supplier documentation, including certificates of analysis. The lack of standardized quality controls raises concerns about identity, purity, and actual content in products marketed online.
In laboratory settings, SR9009 is commonly identified by its molecular structure and its interaction with REV-ERB receptors. Vendors may list it under synonyms such as Stenabolic or REV-ERB agonist, but those names do not define purity or identity. Analytical confirmation typically uses high-performance liquid chromatography with ultraviolet detection or liquid chromatography–mass spectrometry. A reference standard is needed to compare retention time and mass spectrum, because the compound can be confused with related research chemicals.
Physicochemical behavior influences handling. SR9009 is described as a solid with limited aqueous solubility, so organic solvents such as dimethyl sulfoxide or ethanol are common in research stock solutions. Aqueous dilution can produce precipitates if the organic content is too low. Light, heat, and repeated freeze-thaw cycles may affect stability. Storage recommendations usually specify a desiccated freezer environment protected from light, but exact stability data depend on the formulation and matrix.
Detection in biological samples can be complicated by rapid metabolism and low circulating concentrations. Some studies report phase I and phase II metabolites, and analytical methods may need to target those species in addition to the parent compound. Immunoassays are not broadly available, so mass spectrometry remains the main confirmatory approach. For anti-doping testing, laboratories look for SR9009 and its metabolites using validated LC-MS methods. Open questions include how long metabolites remain detectable and how different routes of administration alter detection windows.
In laboratory settings, SR9009 is typically characterized by liquid chromatography–mass spectrometry (LC-MS) or high-performance liquid chromatography with ultraviolet detection (HPLC-UV). These methods can confirm identity and estimate purity, but they require reference standards for accurate quantification. Because SR9009 is not a licensed pharmaceutical, no harmonized pharmacopeial monograph exists. Laboratories often validate in-house methods for matrices such as plasma, urine, or cell culture media. Sample preparation may involve protein precipitation or liquid-liquid extraction before analysis.
| Property | Value | Notes |
|---|---|---|
| Appearance | White to off-white solid | Visual inspection is not sufficient for identity. |
| Solubility | Soluble in DMSO and ethanol | Low solubility in water. |
| Typical storage | -20 °C, desiccated, dark | Protect from repeated temperature changes. |
| Common analytical method | LC-MS or HPLC-UV | Reference standard required for comparison. |
| Common synonyms | SR9009; Stenabolic; REV-ERB agonist | Vendor naming may vary. |
SR9009 is not approved as a medicine by major regulatory agencies. It is commonly sold as a research chemical, a category that may fall outside customary drug approval and quality rules. In sports, the World Anti-Doping Agency lists SR9009 as a prohibited substance. Athletes who use it can face sanctions if it is detected in a sample. Legal status varies by country, and importation may be restricted. Enforcement practices differ across borders.
Detection of SR9009 in biological samples usually employs liquid chromatography coupled with tandem mass spectrometry. This method can identify the parent compound and sometimes metabolites in urine or blood. Because exposure can be low and clearance may be rapid, sample timing and limits of detection matter. Laboratories validate assays for sensitivity and specificity. Results are interpreted alongside chain-of-custody and quality-control records. Urine is the common matrix for anti-doping analysis, while blood may be used in research settings.
Stability depends on physical form, temperature, light exposure, and solvent. Solid SR9009 is generally stored cold and dry, with protection from light to limit degradation. Dimethyl sulfoxide stocks are common for laboratory work, but repeated freeze-thaw cycles can reduce compound integrity. Aqueous solutions may be less stable than organic stocks, and the ethyl ester in the structure can be susceptible to hydrolysis under certain conditions. Researchers typically validate storage conditions and recheck purity before quantitative experiments, especially when using archived material.
Regulatory treatment of SR9009 varies by country and region. It is not approved as a pharmaceutical, and several jurisdictions restrict its sale for human consumption. Some authorities classify it as a research chemical, a prescription-only substance, or a prohibited performance-enhancing agent in sport. Purchasers may encounter certificates of analysis, but these documents do not guarantee identity, purity, or legality. In research settings, institutional safety reviews and controlled procurement help ensure that materials are handled under appropriate oversight. The absence of harmonized rules means that legal status can change and requires verification.
Analytical identification of SR9009 typically relies on liquid chromatography coupled with tandem mass spectrometry. In biological samples, researchers first separate the compound from matrix components using protein precipitation, liquid-liquid extraction, or solid-phase extraction. High-performance liquid chromatography with ultraviolet detection and nuclear magnetic resonance spectroscopy can support structural confirmation of reference materials. Because SR9009 is a small, relatively lipophilic molecule, reverse-phase columns and acidic mobile phases are common. Laboratories often include isotope-labeled internal standards to improve quantification and to correct for ion suppression.
SR9009 is supplied as a solid research chemical, often in milligram quantities. Laboratories typically weigh it in a controlled environment because fine powders can disperse. Stock solutions are commonly prepared in dimethyl sulfoxide and stored in small aliquots to reduce freeze-thaw cycles. Personal protective equipment and chemical fume hoods are standard when handling unknown or potent compounds. These practices address laboratory safety rather than human use.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.
SR9009 stability depends on temperature, moisture, light, and solvent. Solid material is generally kept cool and dry, while solutions may require protection from repeated warming and cooling. Degradation can appear as color changes, precipitate, or new chromatographic peaks. Researchers should follow supplier instructions and their own stability data. Long-term storage conditions for human use have not been established because the compound lacks approved clinical formulation.
9 September South Vietnamese officials reported that nearly 5,000 South Vietnamese civilians have been killed by PAVN/VC terror during 1969. Funeral services for Ho Chi Minh were held in Ba Đình Square, Hanoi attended by more than 250,000 mourners. Foreign dignitaries in attendance included Alexei Kosygin, Premier of the Soviet Union, Li Xiannian, Vice Premier of China, Gustáv Husák, General Secretary of the Communist Party of Czechoslovakia, Ignacy Loga-Sowiński, Deputy Premier of Poland, Ion Gheorghe Maurer, Prime Minister of Romania, Sihanouk and Souvanna Phouma.
In June 1998, Caldwell Dyson was selected by NASA, and began NASA training two months later, in August 1998. Her astronaut candidate training included orientation briefings and tours, numerous scientific and technical briefings, intensive instruction in Shuttle and International Space Station (ISS) systems, physiological training, ground school to prepare for T-38 flight training, as well as learning water and wilderness survival techniques. Completion of this training and evaluation qualified her for flight assignment as a mission specialist. In 1999, Caldwell Dyson was assigned to the Astronaut Office ISS Operations Branch as a Russian Crusader, participating in the testing and integration of Russian hardware and software products developed for ISS. In 2000, she was assigned prime crew support astronaut for the ISS Expedition 5 crew, serving as their representative on technical and operational issues throughout the training and on-orbit phase of their mission. During ISS Expeditions 4 through 6, Caldwell Dyson served as an ISS spacecraft communicator (CAPCOM) inside Mission Control. In 2003, she made a transition to the Astronaut Shuttle Operations Branch and was assigned to flight software verification in the Shuttle Avionics Integration Laboratory and worked supporting launch and landing operations at Kennedy Space Center, Florida. Caldwell Dyson also served as Lead CAPCOM for Expedition 11.
==== Pneumococcal vaccine ==== In 2010, as part of a 10-year pneumococcal vaccine Advance Market Commitment, the companies GlaxoSmithKline (GSK) and Pfizer were both allocated $225 million in AMC subsidies to provide 30 million doses annually at a maximum tail price of $3.50 per dose ($10.50 per child for three doses). In 2011, Médecins Sans Frontières (MSF) recommended that Gavi change the ways in which it procures vaccines. MSF argued that the Advance Market Commitment had transferred more money to GSK and Pfizer than the Gavi grants had transferred to low-cost suppliers for technology transfer and product development. MSF said that large pharmaceutical multinationals had been found to put very high markups on prices, and internationally certified vaccine could be made for about 40% less cost by smaller companies in India and China, despite patent-related obstacles. In January 2015, MSF also called upon GSK and Pfizer to cut the price of the pneumococcal vaccine to US$5 per child in developing countries, a price they estimated as competitive. They said that, as Pfizer had made $16 billion in revenue on pneumococcal vaccine in the last four years, a larger price cut would be affordable. In early 2016, they ran the "A fair shot" campaign to pressure GSK and Pfizer to drop prices. Pfizer said that they were already selling the vaccine at "far below" cost, while GSK said that the price enabled them to "just about" cover their costs, and "To discount it further would threaten our ability to supply it to these countries in the long-term".
In the 1970s, biscuit manufacturers began using micro-aeration to process chocolate for moulded products. This was a cost-saving measure: with less chocolate, the same volume of coated biscuit could be maintained. In 1981 or 1983, Cadbury released Wispa, an aerated chocolate with a more chunky shape than Aero bars, made using a secret, non-patented process. The launch of Wispa was successful, but it soon encountered manufacturing difficulties and was temporarily withdrawn from the market. While Wispa was off the market, Rowntree's developed and launched a chunky Aero which they successfully launched and was still being sold as of 2008. Wispa was discontinued in the early 2000s so Cadbury could bring in a new aerated chocolate product aligned with the Cadbury Dairy Milk brand: Dairy Milk Bubbly. Following an internet campaign in 2007, Cadbury reintroduced Wispa. Today, Aero is manufactured by Nestlé, the brand having been acquired by Nestlé during a 1988 takeover of Rowntree's. As of 2023, other brands of aerated chocolate includes Mirage and Galaxy.

==== Positive criminology and positive victimology ==== Positive criminology and positive victimology are conceptual approaches, developed by the Israeli criminologist Natti Ronel and his research team, that follow principles of positive psychology and apply them into the fields of criminology and victimology, respectively. Positive criminology and victimology both place an emphasis on social inclusion and on unifying and integrating forces at individual, group, social and spiritual levels that are associated with the limiting of crime and recovery from victimization. In traditional approaches, the study of crime, violence and related behaviors emphasizes the negative aspects in people's lives that are associated with deviance, criminality and victimization. A common understanding is that human relationships are affected more by destructive encounters than by constructive or positive ones. Positive criminology and victimology argue that a different approach is viable, based on three dimensions – social integration, emotional healing and spirituality – that constitute positive direction indicators.
=== Phylogeny === Viola is one of about 25 genera and about 600 species in the large eudicot family Violaceae, divided into subfamilies and tribes. While most genera are monotypic, Viola is a very large genus, variously circumscribed as having between 500 and 600 species. Historically it was placed in subfamily Violoideae, tribe Violeae. But these divisions have been shown to be artificial and not monophyletic. Molecular phylogenetic studies show that Viola occurs in Clade I of the family, as Viola, Schweiggeria, Noisettia and Allexis, in which Schweiggeria and Noisettia are monotypic and form a sister group to Viola.
== Management == Medical management of VHF patients may require intensive supportive care. Antiviral therapy with intravenous ribavirin may be useful in Bunyaviridae and Arenaviridae infections (specifically Lassa fever, RVF, CCHF, and HFRS due to Old World Hantavirus infection) and can be used only under an experimental protocol as IND approved by the U.S. Food and Drug Administration (FDA). Interferon may be effective in Argentine or Bolivian hemorrhagic fevers (also available only as IND).

=== Europe === Skin whitening practices have been documented in ancient Greece and Rome. Bleaching cosmetics often incorporated white lead carbonate and mercury as lightening agents. These products were ultimately known to cause skin erosion. Skin whitening was frequently documented during the Elizabethan era. Queen Elizabeth's own usage of skin lighteners became a prominent standard of beauty. According to medieval historians, light skin was an indicator of aristocracy and higher socioeconomic class, as laborers were more frequently exposed to outdoor sunlight. Men and women lightened their skin superficially and chemically, using white powder and Venetian ceruse, respectively. Venetian ceruse consisted of a lead and vinegar mixture, known to cause hair loss, skin corrosion, muscle paralysis, tooth deterioration, blindness, and premature aging. Venetian ceruse was also reported as a source of lead poisoning. Lye and ammonia, found in other skin whiteners, compounded the toxic effects of lead. Other practices done in the name of skin whitening included washing one's face in urine and ingesting wafers of arsenic.
Chain Home radar installations were normally composed of two sites. One compound contained the transmitter towers with associated structures, and a second compound, normally within a few hundred metres distance, contained the receiver masts and receiver equipment block where the operators (principally WAAF, Women's Auxiliary Air Force) worked. The CH system was, by modern terminology, a "bistatic radar", although modern examples normally have their transmitters and receivers far more widely separated. The transmitter antenna consisted of four steel towers 360 feet (110 m) tall, set out in a line about 180 feet (55 m) apart. Three large platforms were stationed on the tower, at 50, 200 and 350 feet off the ground. A 600 ohm transmission cable was suspended from the top platform to the ground on either side of the platform (only on the inside of the end towers). Between these vertical feed cables were the antennas proper, eight half-wave dipoles strung between the vertical cables and spaced ½ of a wavelength apart. They were fed from alternating sides so the entire array of cables was in-phase, given their ½ wavelength spacing. Located behind each dipole was a passive reflector wire, spaced 0.18 wavelength back. The resulting curtain array antenna produced a horizontally polarised signal that was directed strongly forward along the perpendicular to the line of the towers. This direction was known as the line of shoot, and was generally aimed out over the water.

Liquid chromatography–mass spectrometry is common for identity and purity checks. High-performance liquid chromatography with ultraviolet detection can also be used. Both methods require a suitable reference standard.
The solid is usually kept desiccated at -20 °C or lower and protected from light. Stock solutions are aliquoted to limit freeze–thaw cycles. Aqueous solutions are not generally recommended for long-term storage.
Laws differ by country and by intended use. It is not an approved medicine, and many vendors sell it as a research chemical. Purchasers are responsible for confirming local restrictions.
It is usually detected by LC-MS or HPLC-UV against a reference standard. In biological matrices, metabolite targeting can improve detection. No universal immunoassay is widely available.
