3-oxo-4-androstene-17beta-carboxylic acid

3-oxo-4-androstene-17beta-carboxylic acid is a steroidal small molecule and active pharmaceutical ingredient (API) intermediate produced by Jiangsu Jiaerke Pharmaceuticals. It serves as a critical structural precursor in the industrial synthesis of various steroid-based medications. Most notably, it is a key intermediate in the production of 5-alpha reductase inhibitors such as finasteride and dutasteride, which are used to treat benign prostatic hyperplasia (BPH) and androgenetic alopecia. As an intermediate, its primary role is as a chemical building block in pharmaceutical manufacturing rather than as a finished therapeutic agent. It is typically supplied as a bulk API for further chemical transformation into final drug products.
