Molecule Structure Image



Diphenylamine is used as a pre or postharvest scald inhibitor for apples.Its anti-scald activity is the result of its antioxidant properties, which protect the apple skin from the oxidation products of alpha-farnesene during storage.They are used as "antiozinates" in the manufacture of rubber products, reflecting the antioxidant nature of aniline derivatives. With sulfur, it gives phenothiazine, a precursor to certain pharmaceuticals. Alkylated diphenylamines function as antioxidants in lubricants, approved for use in machines, in which contact with food is not ruled out.
