Description

(10A)-Androst-4-En-3-One CAS NO 23124-52-9 is a high-purity steroid intermediate, also known as 10α-Androst-4-ene-3,17-dione, valued for its defined stereochemistry at the C-10 position. This specificity makes it a crucial building block in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs) and reference standards. It is primarily required by pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions engaged in steroid chemistry and hormone research.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of steroidal drugs, including corticosteroids, anabolic agents, and hormone therapies.
• Research & Development: Used as a reference standard and starting material in academic and industrial research exploring steroid metabolism and novel synthetic pathways.
• Fine Chemical Synthesis: Serves as a chiral building block for creating specialized steroid derivatives with potential biological activity.
• Analytical Standard: Employed in analytical methods such as HPLC and GC for quality control and impurity profiling in steroid manufacturing.
