Identification, synthesis and characterization of avanafil process impurities and determination by UPLC

Identification, synthesis and characterization of avanafil process impurities and determination by UPLC

Avanafil is a phosphodiesterase type 5 inhibitor which is used to treat erectile dysfunction in men. The process-related impurities of avanafil were investigated, and four kinds of impurities in several laboratory batches with a content of 0.29-1.63% were detected by the newly developed gradient ult...
