Finasteride is a 5-α-reductase inhibitor with a steroidal skeleton and an amide group in its structure. It was subjected to forced degradation to observe its stability under stress conditions according to ICH guidelines. It was found to be stable to base and peroxide. However, in acid medium, three degradation products were observed. All of them were isolated from the reaction mixture by preparative HPLC. Their structures were elucidated by extensive analysis of 1D, 2D NMR spectra and HRMS. To best of our knowledge, none of them have been reported elsewhere.
