N-Nitrosodiphenylamine is a yellow or orange-brown solid with no odour. It is soluble in acetone, ethanol, benzene, and ethylene dichloride. Its flash point and flammability limits are unknown. It is not a naturally occurring substance; it is a man-made chemical that was used in rubber compounding as a retarder to prevent premature vulcanisation of rubber compounds during mixing and other processing operations. It was generally used with sulphenamide accelerators in tyre compounds and other mechanical goods.
N-Nitrosodiphenylamine was also used as an intermediate in the manufacture of p-nitrosodiphenylamine, which was subsequently used to produced N-phenyl-p-phenylenediamine and other rubber-processing chemicals. American manufacturers stopped producing N-nitrosodiphenylamine in the early 1980s because new and more efficient chemicals were found to replace it. It also had several undesirable side effects which do not occur with replacement chemicals.
N-nitrosodiphenylamine is also known as diphenylnitrosoamine, N-nitroso-n-phenylaniline, N-nitroso-n-phenylbenzenamine, N,n- diphenylnitrosoamine, nitrous diphenylamide, NDPA, and NDPhA. Research N-Nitrosodiphenylamine
