Description

D4-Androsterone CAS NO 361432-60-2 is a deuterated analog of the endogenous steroid hormone androsterone, where four hydrogen atoms are replaced with deuterium. This isotopic labeling provides a stable, non-radioactive tracer essential for advanced metabolic and pharmacokinetic studies. It is a critical reference standard and intermediate for researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors who require high-purity, isotopically labeled compounds.

Application

• Internal Standard for LC-MS/MS: Used as a stable isotope-labeled internal standard in quantitative bioanalysis to ensure accuracy and precision in mass spectrometry.
• Metabolic Pathway Tracing: Enables detailed investigation of steroid hormone metabolism, biosynthesis, and degradation pathways in research settings.
• Pharmaceutical Reference Material: Serves as a certified reference standard for method development, validation, and quality control in drug discovery and development.
• Deuterated Drug Intermediate: Acts as a key synthetic building block for the preparation of deuterated drug candidates, which can offer improved metabolic stability.
• Clinical Research & Diagnostics: Supports clinical studies and the development of diagnostic assays for endocrine disorders and hormonal imbalances.
• Forensic & Doping Control Analysis: Employed in specialized laboratories for the precise detection and confirmation of steroid profiles.
