p-Phenylenediamine (1,4-Phenylenediamine; PPD) (CAS: 106-50-3) is one of the simplest aromatic diamine. It has been described as gray “light brown” which may result from exposure to air. It can be used for making azo dyes, high-molecule polymers and can also be used for the production of fur dyes, rubber antioxidants and photo developer and is mainly used for Kevlar, azo dyes, sulfur dyes, acid dyes. It can also be used as the raw material of cosmetic hair p-Phenylenediamine series, gasoline polymerization inhibitor and developer. p-Phenylenediamine, as a chemical dye, is currently permitted for use in hair dye production, but there is a clear usage limits. Used as organic intermediates or pharmaceutical intermediates.
Dust may form explosive mixture with air. A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, acid chlorides; acid anhydrides; chloroformates, and strong bases. Incompatible with organic anhydrides; isocyanates, aldehydes. Heat and light contribute to instability. Keep away from metals.
