4-chloro-2,5-dimethoxyaniline

4-Chloro-2,5-dimethoxyaniline (CAS 6358-64-1) is an aromatic amine intermediate used in the synthesis of azo dyes and pigments. It functions as a diazonium-forming compound, enabling the production of colorants with specific hue and fastness profiles. These colorants are targeted at textile, leather, paper, and printing applications. In textile dyeing, it serves as a key coupling component in the manufacture of azo dyes applied to cotton and synthetic fibers.

Precise shade reproducibility is a formulation requirement for these materials. Paper and leather colorant producers use it to develop dyes with strong substrate affinity and resistance to fading under processing conditions. In printing ink formulations, it contributes to pigment intermediates that meet the color strength and lightfastness demands of packaging substrates. It also supports polymerization initiation processes in specialty chemical manufacturing.

This compound is utilized where controlled radical generation is required for specific reactions. 4-Chloro-2,5-dimethoxyaniline is supplied as a solid, typically in powder or crystalline form for industrial use. Technical grade is the standard commercial offering, with purity specifications commonly ranging from 98% upward to meet dye intermediate manufacturing requirements. Bulk quantities are available for industrial procurement.

Smaller packaging options are also provided for formulation development and quality evaluation purposes. This ensures that manufacturers can test the material before moving to full-scale production cycles.
