Description

18-Hydroxytestosterone is a hydroxylated derivative of the endogenous androgen testosterone, identified by CAS NO 7150-17-6. This compound serves as a crucial intermediate and reference standard in pharmaceutical research and development, particularly in the study of steroid metabolism and hormone biosynthesis. It is essential for pharmaceutical manufacturers, research institutions, and analytical laboratories engaged in endocrinology, drug discovery, and the production of high-purity steroid APIs.

Application

• Pharmaceutical Intermediate: A key synthetic precursor in the manufacture of specialized steroid-based active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference compound in studies investigating androgen metabolism, enzyme activity (e.g., cytochrome P450), and metabolic pathways.
• Analytical Standard: Serves as a high-purity certified reference material (CRM) for quality control and method validation in HPLC, GC-MS, and LC-MS analyses.
• Endocrinology & Diagnostics: Employed in the development and calibration of diagnostic assays and kits for hormone level testing.
• Academic & R&D: A vital tool for universities and contract research organizations (CROs) exploring novel therapeutic agents and steroid biochemistry.
