Description

N-[3-Amino-4-[[7-[[4-[[4-[[2-amino-4-[(sodiooxycarbonylmethyl)amino]phenyl]azo]phenyl]amino]phenyl]azo]-8-hydroxy-6-sodiosulfo-2-naphthalenyl]azo]phenyl]glycine sodium salt is a high-purity, complex azo dye intermediate essential for producing vibrant and stable colorants. This compound matters for manufacturers requiring precise chromophore structures to achieve specific shades and performance characteristics in demanding applications. It is primarily needed by industrial-scale producers of dyes and pigments for textiles, inks, and specialty coatings who prioritize batch-to-batch consistency and technical purity.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the synthesis of high-grade reactive dyes for cotton and other cellulosic fibers.
• Textile Colorant Production: Used in manufacturing dyes that offer excellent wash-fastness and brightness for the textile industry.
• Specialty Ink Formulations: Serves as a precursor for pigments used in high-performance inks for packaging and digital printing.
• Industrial Pigment Synthesis: Employed in creating complex organic pigments for plastics, paints, and coatings.
• Research & Development: Utilized in chemical R&D for developing new chromophores and studying azo dye chemistry.
• Fine Chemical Manufacturing: Acts as a specialized intermediate in the production of other value-added chemical products.
