Para-Chloroaniline (p-CA)
Para-chloroaniline is a halogenated aromatic amine that serves as a diazonium-forming component in the synthesis of fast, light-fast azo dyes for textiles, leather, and printing inks. The chloro substituent enhances the electron-withdrawing character, producing azo dyes with improved lightfastness compared to unsubstituted aniline derivatives. Chemzip provides high-purity p-CA to dye and pigment manufacturers globally.
