STEROIDS (seco-steroids C07C)

Introduced: July 1974

Description

C07J covers the chemical synthesis, preparation, and characterization of steroid compounds and their derivatives. This subclass includes methods for producing natural steroids (such as cholesterol, bile acids, and sex hormones) and synthetic steroid analogues, as well as chemical transformations affecting the steroid nucleus or side chains. The classification encompasses both the isolation and synthetic modification of steroid structures across pharmaceutical, cosmetic, and industrial applications.
