N-Nitroso Albendazole Impurity A

N-Nitroso Albendazole Impurity A is a nitrosamine-related impurity associated with the anthelmintic drug albendazole. It can potentially form through nitrosation of albendazole or related compounds under certain conditions. Because nitrosamine impurities may present a genotoxic and carcinogenic concern, their presence in pharmaceutical products is closely monitored and controlled by regulatory authorities. Detection and quantification are generally performed using sensitive analytical techniques such as LC–MS/MS.
