Description

Hexasodium 7,7'-[1,4-Phenylenebis[Imino(6-Chloro-1,3,5-Triazine-4,2-Diyl)Imino[2-[(Aminocarbonyl)Amino]-4,1-Phenylene]Azo]]Bis(Naphthalene-1,3,6-Trisulphonate) is a high-purity, water-soluble anionic dye intermediate characterized by its complex polyazo and triazine-based structure. This compound matters for its exceptional ability to form strong covalent bonds with cellulosic and synthetic fibers, making it a critical precursor for high-performance reactive dyes. Industrial manufacturers and specialty chemical formulators need this product to produce dyes with superior wash-fastness, light-fastness, and brilliant color properties for textiles, inks, and specialty coatings.

Application

• Reactive Dye Synthesis: Primary intermediate for manufacturing high-grade reactive dyes used in cotton, viscose, and other cellulosic fiber dyeing and printing.
• Textile Industry: Key component in producing dyes that offer excellent fixation, bright shades, and outstanding fastness properties to washing and light.
• Inkjet Inks: Used in the formulation of specialty inks where high color strength and stability are required.
• Leather Coloring: Employed in the production of dyes for leather finishing to achieve durable and vibrant colors.
• Paper Dyeing: Suitable for the coloration of specialty papers requiring high color fastness.
• Research & Development: Serves as a valuable building block in chemical research for developing new chromophores and functional dyes.
