Description

Androst-5-En-7-One,3Beta,17Beta-Bis(Acetyloxy) is a high-purity steroid derivative, specifically a diacetylated form of a key androstane intermediate. This compound is valued for its role as a critical building block in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs) and fine chemicals. It is primarily required by pharmaceutical R&D laboratories, contract manufacturing organizations (CMOs), and fine chemical producers engaged in the development of steroidal drugs and reference standards.

Application

• Pharmaceutical Intermediate: A key synthetic precursor in the multi-step production of steroidal hormones and related therapeutic agents.
• Research & Development: Used in academic and industrial laboratories for investigating steroid metabolism, structure-activity relationships (SAR), and novel synthetic pathways.
• Reference Standard: Serves as a certified reference material (CRM) for analytical method development, validation, and quality control in pharmaceutical analysis.
• Fine Chemical Synthesis: Employed in the custom synthesis of specialized steroid derivatives for biochemical research and high-value material science applications.
