Description

19-Norandrosterone-D5 is a deuterium-labeled internal standard of the endogenous steroid metabolite 19-norandrosterone. This high-purity compound is critical for ensuring the accuracy and reliability of analytical methods in anti-doping control and clinical research. It is primarily utilized by analytical laboratories, research institutions, and pharmaceutical companies involved in steroid metabolism studies and the development of sensitive detection assays.

Application

• Quantitative Internal Standard for LC-MS/MS: Essential for the precise quantification of 19-norandrosterone in human urine and serum samples in anti-doping testing.
• Metabolic Pathway Research: Used as a tracer in studies investigating the biosynthesis and degradation pathways of anabolic-androgenic steroids.
• Method Development & Validation: Serves as a critical reference material for developing, calibrating, and validating high-sensitivity gas chromatography or liquid chromatography mass spectrometry methods.
• Quality Control in Reference Material Production: Employed in the manufacturing and certification of certified reference materials (CRMs) for forensic and clinical laboratories.
• Doping Control Research: Supports research aimed at improving detection windows, understanding steroid profiles, and identifying new biomarkers for drug abuse.
