Description

Epitestosterone Sulfate-D3 Triethylamine Salt is a high-purity, stable deuterated salt form of epitestosterone sulfate, a key reference standard and metabolite. This compound is essential for ensuring analytical accuracy and reliability in quantitative bioanalysis, particularly for doping control and clinical research. It is primarily used by pharmaceutical R&D laboratories, forensic toxicology facilities, and manufacturers of diagnostic kits and reference materials.

Application

• Internal Standard for LC-MS/MS: Serves as a critical deuterated internal standard for the precise quantification of epitestosterone and its metabolites in biological matrices like urine and serum.
• Doping Control Analysis: Used in anti-doping laboratories for method development, validation, and routine testing to detect the misuse of testosterone and related steroids in sports.
• Clinical Research & Endocrinology: Supports studies investigating androgen metabolism, endocrine disorders, and the physiological role of epitestosterone.
• Pharmaceutical Metabolite Studies: Employed in drug development for pharmacokinetic and metabolic profiling of steroidal compounds.
• Forensic Toxicology: Aids in the accurate identification and measurement of steroid profiles in forensic casework.
• Reference Standard Manufacturing: Used as a primary material to calibrate equipment and qualify secondary reference standards for commercial diagnostic assays.

Quality Control

Every batch of Epitestosterone Sulfate-D3 Triethylamine Salt is manufactured under strict quality management systems and undergoes comprehensive analytical testing. We guarantee high chemical and isotopic purity, with specifications typically meeting or exceeding the requirements for certified reference materials. A detailed Certificate of Analysis (COA) providing batch-specific data from NMR, HPLC, and MS is supplied with each shipment to ensure traceability and compliance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry, cool place. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to keep the container under an inert atmosphere. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
