Description

6-B-Hydroxy Testosterone-D3 is a high-purity, deuterium-labeled steroid reference standard. This compound is critical for ensuring analytical accuracy and method validation in sophisticated laboratory testing. It is primarily required by pharmaceutical research, clinical diagnostic, and anti-doping control laboratories for use as an internal standard in mass spectrometry.

Application

• Internal Standard for LC-MS/MS: Used for the precise quantification of testosterone and its metabolites in biological matrices.
• Pharmaceutical R&D: Serves as a reference material in the development and validation of bioanalytical methods for steroid-based drugs.
• Clinical Diagnostics: Enables accurate measurement of hormonal levels in patient serum or plasma samples.
• Anti-Doping Analysis: Essential for World Anti-Doping Agency (WADA)-compliant testing to detect testosterone abuse in sports.
• Metabolic Studies: Employed in research to track and understand the metabolic pathways of testosterone.
• Quality Control: Acts as a certified reference material (CRM) for calibrating laboratory equipment and ensuring result reproducibility.
