Description

Androst-5-En-17-One, 16-Bromo-3,7-Dihydroxy-, (3Beta,7Beta,16Alpha)- (9Ci) is a high-purity, synthetically modified steroid derivative of significant interest in advanced pharmaceutical research and development. This compound matters as a critical chiral building block and intermediate for the synthesis of novel therapeutic agents, particularly in the fields of endocrinology and oncology. It is primarily needed by R&D laboratories, pharmaceutical manufacturers, and fine chemical suppliers engaged in the production of specialized steroid-based APIs and reference standards.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the multi-step synthesis of novel steroid-based active pharmaceutical ingredients (APIs) targeting hormonal pathways.
• Biochemical Research: Used as a reference standard or probe in metabolic studies, enzyme inhibition assays, and receptor binding research to investigate steroid hormone action and metabolism.
• Fine Chemical Synthesis: Serves as a versatile precursor for the preparation of more complex, brominated steroid analogs with potential biological activity.
• Academic & Contract Research: Employed in university and CRO settings for method development, structure-activity relationship (SAR) studies, and the discovery of new molecular entities.
