Quantitative Study of Impurities in Enzalutamide and Identification, Isolation, Characterization of Its Four Degradation Products Using HPLC, Semi-preparative LC, LC/ESI–MS and NMR Analyses

Enzalutamide was recently approved for the treatment of castration-resistant prostate cancer. In this study, the related substances in enzalutamide bulk substance were analyzed qualitatively and quantitatively. Four degradation products (Oxi, A9, P1 and P2) of enzalutamide were isolated using semi-p...
