4-Chloro-2,5-dimethoxyaniline

4-Chloro-2,5-dimethoxyaniline (CAS 6358-64-1, EC 228-782-0) is an aromatic amine compound also referenced as 2,5-dimethoxy-4-chloroaniline. It carries no assigned E-code and is classified under HS code 2921.42.9000 within the broader category of pigments and colorants intermediates.

In the printing and packaging sector, this compound serves as a diazonium coupling component in the synthesis of azo pigments, where its methoxy and chloro substituents control the final hue and fastness properties of the colorant. It also functions as a polymerization initiator in textile and paper treatment processes, contributing to the formation of durable surface coatings and dyed fiber structures.

This material is supplied as a crystalline powder and is subject to REACH registration requirements applicable to EU-based procurement. Buyers should confirm purity grade specifications and request a full safety data sheet prior to ordering, as handling requirements apply to aromatic amine derivatives.
