Description

Androstenediol-3-Acetate CAS NO 1639-43-6 is a key steroid intermediate and a derivative of androstenediol, characterized by its acetylated 3-hydroxy group. This chemical modification enhances its stability and alters its metabolic profile, making it a valuable precursor in advanced pharmaceutical synthesis. It is primarily required by research institutions and manufacturers in the pharmaceutical and biotechnology sectors for the development of steroid-based therapeutics and reference standards.

Application

• Pharmaceutical Intermediate: A critical building block in the multi-step synthesis of more complex steroid hormones and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard or substrate in metabolic pathway studies, enzyme inhibition assays, and receptor binding research.
• Hormone Analog Development: Serves as a starting material for the research and development of novel androgen and anabolic steroid analogs.
• Analytical Standard: Employed in analytical laboratories for method development, calibration, and quality control testing of steroid compounds via HPLC, GC-MS, or LC-MS.
