Description

Epitestosterone Glucuronide is a high-purity reference standard and biochemical reagent, specifically the glucuronide conjugate of the endogenous steroid epitestosterone. This compound is of critical importance in analytical chemistry and anti-doping research for the accurate quantification and confirmation of epitestosterone levels. It is primarily required by pharmaceutical R&D laboratories, forensic toxicology units, and manufacturers of diagnostic kits for steroid profiling and sports drug testing.

Application

• Reference Standard for Doping Control: Serves as a primary certified reference material (CRM) for the calibration and validation of LC-MS/MS and GC-MS methods in anti-doping laboratories to detect and confirm the presence of epitestosterone.
• Pharmaceutical Metabolite Research: Used in studies investigating the metabolism, pharmacokinetics, and excretion pathways of endogenous and synthetic androgenic steroids.
• Diagnostic Kit Manufacturing: A key raw material in the production of immunoassay kits and other in-vitro diagnostic (IVD) devices designed for hormonal analysis and steroid panel testing.
• Forensic Toxicology: Employed as a qualitative and quantitative standard in forensic analyses to determine steroid abuse and for expert witness testimony support.
• Biochemical Research: Utilized in enzymatic studies related to glucuronidation pathways, specifically involving UGT enzymes, to understand steroid hormone conjugation and deconjugation.
• Quality Control (QC) in API Production: Acts as a system suitability standard and impurity marker in the quality control of steroid-based active pharmaceutical ingredients (APIs).
