Description

Epitestosterone Sulfate Triethylamine Salt is a high-purity, chemically modified reference standard of the endogenous steroid epitestosterone. This compound is specifically designed for analytical and research applications where precise quantification and reliable performance are critical. It is primarily utilized by pharmaceutical R&D laboratories, clinical research organizations, and forensic testing facilities for method development, calibration, and quality control in steroid analysis.

Application

• Reference Standard for Analytical Chemistry: Used as a certified reference material (CRM) for the calibration of LC-MS/MS, GC-MS, and HPLC systems in quantitative bioanalysis.
• Anti-Doping Research & Testing: Essential for developing and validating assays to detect and quantify epitestosterone and its metabolites in biological samples for sports drug testing programs.
• Endocrinology & Steroid Metabolism Studies: Serves as a key reagent in research investigating steroid biosynthesis pathways, hormone ratios (e.g., Testosterone/Epitestosterone or T/E ratio), and metabolic disorders.
• Pharmaceutical Impurity Profiling: Employed in the identification and quantification of potential steroid-related impurities or degradation products in active pharmaceutical ingredients (APIs) and finished drug products.
• Clinical Diagnostic Assay Development: Used to establish standard curves and ensure accuracy in diagnostic kits and laboratory-developed tests (LDTs) for hormonal profiling.
• Forensic Toxicology: A critical component in the confirmatory analysis of anabolic-androgenic steroids in forensic casework, providing legally defensible results.

Quality Control

Our Epitestosterone Sulfate Triethylamine Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, LC-MS for identity confirmation, and residual solvent analysis, to ensure it meets the stringent requirements for use as a reference material. A detailed Certificate of Analysis (COA) providing batch-specific data is supplied with every order.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
