Description

Oxandrolone 17-Sulfate is a chemically modified derivative of the anabolic steroid oxandrolone, designed for enhanced stability and specific pharmaceutical applications. This compound is valued for its role as a key intermediate in the synthesis of high-purity active pharmaceutical ingredients (APIs) and for research into novel therapeutic formulations. It is primarily utilized by pharmaceutical manufacturers, research institutions, and fine chemical suppliers engaged in steroid chemistry and advanced drug development.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of oxandrolone and related anabolic steroid APIs under Good Manufacturing Practice (GMP) conditions.
• Research & Development: Used in academic and industrial laboratories for metabolic studies, structure-activity relationship (SAR) research, and the development of new steroid-based therapies.
• Reference Standard: Serves as a high-purity analytical standard for quality control testing, method validation, and regulatory compliance in pharmaceutical analysis.
• Fine Chemical Synthesis: Employed in custom synthesis and contract manufacturing for producing specialized steroid derivatives and prodrugs.
