p-Phenylenediamine, identifiable by CAS 106-50-3, functions as a primary aromatic amine intermediate used primarily in the synthesis of high-performance aramid fibers and rubber antioxidants. Chemically defined as 1,4-Benzenediamine , this crystalline solid serves as a key precursor for oxidative hair dye formulations and textile dyes due to its ability to form stable colored complexes. The substance, often referred to as PPD or para-Diaminobenzene in industrial chemistry, acts as a crosslinking agent in epoxy resins and a developing agent in photography. We facilitate bulk supply of this organic intermediate with competitive factory pricing, capable of meeting customized specifications for purity and oxidation levels, backed by comprehensive MSDS, TDS, COA documentation.
