Nitroxinil is an anthelmintic agent, which is also an antiparasite. It is highly effective against Fasciola species and its mode of action involves uncoupling the oxidative phosphorylation in liver flukes and also reduces spermatogenesis in surviving flukes, resulting in fewer fertile eggs. Nitroxinil may be used as a reference standard in the determination of nitroxinil in veterinary active pharmaceutical ingredient manufacturing and bovine kidney using reversed-phase high-performance liquid chromatography (RP-HPLC) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS).
