Usage

Applications of 21-hydroxy-20-methylpregn-4-en-3-one (Bisnoralcohol / BA , CAS No. 60966-36-1) as an Intermediate for Progesterone and Ursodeoxycholic Acid

Progesterone, which is a significant steroidal hormone with broad physiological effects such as regulating menstruation, pregnancy support, and promoting embryonic development. As such, this intermediate plays a pivotal role in the pharmaceutical industry. The main functions of ursodeoxycholic acid include: dissolving cholesterol gallstones, promoting bile secretion and excretion, protecting liver function, regulating lipid metabolism, and treating diseases such as bile reflux gastritis. It works by reducing the saturation of cholesterol in bile, promoting the dissolution and excretion of cholesterol, while improving liver function and lipid metabolism, effectively alleviating symptoms of related diseases.
