摘要

N-nitroso-N-methyl-p-toluenesulfonamide (NMTS, diazald, CAS 80-11-5) is a widely used compound for laboratory production of diazomethane. The present results showed that the noncarcinogenic NMTS reacts as a transnitrosating agent with amino nitrogen of secondary amines and amide both in vitro (human gastric juice) and in vivo (rats) to yield N-nitroso compounds. Since all compounds formed (NMOR, NDMA, NPIP, NPZ, NMU) are known animal carcinogens, caution should be taken by users handling NMTS.
