Description

4,16-Dihydroxystanozolol is a synthetic anabolic-androgenic steroid (AAS) derivative, specifically a dihydroxylated analog of stanozolol. This modification enhances its polarity and alters its metabolic profile, making it a compound of significant interest for research and development in pharmaceutical chemistry. It is primarily utilized by research institutions and pharmaceutical developers investigating novel therapeutic agents, metabolic pathways, and structure-activity relationships of steroid hormones.

Application

• Pharmaceutical Research & Development: A key intermediate or reference standard in the synthesis and study of novel anabolic agents and hormone therapies.
• Metabolic Studies: Used in biochemical research to investigate the metabolism, excretion profiles, and biological activity of modified steroid compounds.
• Analytical Reference Standard: Serves as a high-purity certified standard for analytical methods such as HPLC, LC-MS, and GC-MS in forensic, anti-doping, and quality control laboratories.
• Structure-Activity Relationship (SAR) Research: Critical for academic and industrial research aimed at understanding how hydroxyl group substitutions affect the binding affinity and efficacy of steroid molecules.
• Veterinary Pharmaceutical Development: Potential application in the research of therapeutic agents for animal health, particularly in catabolic conditions.
