Diphenylamine 

an aromatic amine, C6H5NHC6H5; colorless crystals that darken upon exposure to light and have a slight characteristic odor. Melting point, 54°C; boiling point, 302°C. It is insoluble in water but soluble in most organic solvents. In industry, it is made by heating aniline, C6H5NH2, with aniline hydrochloride at 200°-230°C. It is used to make dyes and numerous organic intermediates (acridine, carbazole, and others), for stabilizing cellulose nitrate powders, and in colorimetric determination of some oxidizing agents (for example, nitric and nitrous acids).
