Description
N-Methylaniline (CAS 100-61-8, EC 202-870-9, formula C7H9N) is a secondary aromatic amine, also referred to as methylaniline or anilinomethane. It carries no E-code designation and is classified within the aromatic amines group under HS code 29214200.
In polymer and rubber processing, N-Methylaniline functions as a cross-linking agent and antioxidant stabilizer, reacting with peroxides or quinones to inhibit oxidative degradation of polymer chains. In dye and colorant manufacturing, it serves as a key intermediate, where its reactive secondary amine group undergoes coupling reactions to produce azo-based hair dyes and printing ink colorants.
N-Methylaniline is supplied in technical grade as a neat liquid, typically packaged in drums or IBCs. It falls under REACH regulation (EC 1907/2006) and requires an up-to-date Safety Data Sheet for EU trade. Buyers should confirm purity specifications and supplier registration status before procurement.
