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 2026-04-22. Where a claim depends on a specific study, the study is described rather than over-claimed.
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.
Handling recommendations for SR9009 in a laboratory setting include storing the solid at low temperature, protected from light and moisture. The compound is often dissolved in dimethyl sulfoxide or ethanol for experiments. Solutions should be prepared with appropriate personal protective equipment and disposed of according to local rules. Stability data for long-term storage are limited, so stock solutions are typically kept cold and used within defined periods. Records of preparation date and concentration support reproducibility.
Detection of SR9009 in biological samples usually relies on liquid chromatography coupled to tandem mass spectrometry. This approach separates the compound from matrix components and identifies it by mass transitions. Because SR9009 can undergo metabolism, laboratories often look for both parent drug and specific metabolites. Sample preparation may involve protein precipitation or solid-phase extraction. Method validation examines sensitivity, carryover, and interference from related substances, and reference standards are required for accurate calibration.
Storage recommendations for SR9009 reference material typically specify a freezer at -20 °C or lower, with protection from moisture and light. Repeated freeze-thaw cycles can degrade small molecules and introduce variability. Stock solutions in dimethyl sulfoxide are often aliquoted to avoid repeated handling. Stability studies may examine degradation under heat, humidity, and light exposure. The compound's thiophene and nitro groups can participate in reactions that alter analytical signals over time, so such changes affect quantitative results.

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.
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.
SR9009 is generally described as poorly soluble in water and more soluble in organic solvents such as dimethyl sulfoxide and ethanol. Stock solutions are commonly prepared in an organic solvent before dilution into an aqueous buffer or vehicle. Precipitation can occur if the organic fraction is reduced too quickly or if the final concentration exceeds the compound's solubility limit. Sonication or gentle warming may aid dissolution in some protocols, but excessive heat can promote degradation. Container material and pH can also influence observed solubility.
For long-term storage, SR9009 is typically kept as a solid at low temperature, protected from moisture and light. Desiccated conditions limit hydrolysis, while opaque containers reduce photochemical breakdown. Solutions are less stable than solids and are often stored frozen in aliquots to avoid repeated freeze-thaw cycles. Stability data are not standardized across all suppliers, so users should rely on certificate-of-analysis information when available. Degradation may appear as color change, precipitate, or decreased chromatographic purity.
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.
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.

==== Chromatographic methods ==== A variety of chromatographic methods can be used to analyse YTXs. This includes chromatographic techniques coupled to mass spectrometry and fluorescence detectors. All of the chromatographic techniques require a calibration step prior to sample analysis.
strongly acidic cation (SAC), typically featuring sulfonic acid groups, e.g. sodium polystyrene sulfonate or polyAMPS, often used for water softening and demineralization operations. strongly basic anion (SBA), typically featuring quaternary amino groups, for example, trimethylammonium groups, e.g. polyAPTAC), good for silica, uranium, nitrates removal. weakly acidic cation (WAC), typically featuring carboxylic acid groups. An ideal choice for dealkalization part and also for softening streams with high salinity levels. weakly basic anion (WBA), typically featuring primary, secondary, and/or tertiary amino groups, e.g. polyethylene amine. Are effective for demineralization where removal of SiO2 and CO2 are not required. Also effective for acid absorption. Specialised ion-exchange resins are also known such as chelating resins (iminodiacetic acid, thiourea-based resins, and many others). Anion resins and cation resins are the two most common resins used in the ion-exchange process. While anion resins attract negatively charged ions, cation resins attract positively charged ions.
cooling curve A line graph representing the change between different phases of matter, typically from a gas to a solid or a liquid to a solid, as a function of time and temperature; e.g. showing how the temperature of a liquid substance changes over time as it condenses below its freezing point.

In 1990, a team of speleologists uncovered eight mummies, dating back to around 1283 AD, during a rescue excavation in the e 'Asi al-Hadath cave in the Qadisha Valley of Lebanon. The well-preserved spontaneous mummies, including an infant named dubbed Yasmine, offer insights into Maronite villagers' lives during the Mamluk era. The grotto's high altitude and dry conditions naturally mummified the bodies. The discovery provides historical context, aligning with documented Mamluk raids in the region. Artifacts, including pottery with inscriptions, manuscripts, and clothing, suggest a Maronite community, and the mummies' burial practices parallel present-day Lebanese customs. The remains were called "Maronite mummies" because the individuals found in the 'Asi-al Hadath cave were believed to be Maronites, an indigenous Christian community in the region. Some of the mummies have been transferred to the National Museum of Beirut.
==== Donations to spouse's nonprofit organization ==== The Sacramento Bee reported that Jennifer Siebel Newsom's nonprofit organization The Representation Project had received more than $800,000 in donations from corporations that had lobbied the state government in recent years, including PG&E, AT&T, Comcast, and Kaiser Permanente. Siebel Newsom received $2.3 million in salary from the nonprofit since launching it in 2011. In 2021, Governor Newsom said that he saw no conflict in his wife's nonprofit accepting donations from companies that lobby his administration.

According to Minister of the Interior Juan Carlos Bidegain, the law was meant to "guarantee the security, national sovereignty and social and political stability of the country". Although Bukele stated that the law was modeled on the United States' Foreign Agents Registration Act (FARA), critics have compared it to Nicaraguan laws that institute press censorship by shutting down organizations and arresting journalists. Human Rights Watch reported on 16 December 2021 that 91 Twitter accounts belonging to journalists, lawyers, and activists were blocked by Bukele and governmental institutions. In October 2024, when investigative journalists published a report that found that Bukele, his three brothers, wife, and mother had purchased 34 properties valued at US$9 million during Bukele's first presidential term, Bukele referred to the journalists as "imbeciles" and denied accusations of corruption.
