Description

Tetrasodium 3,3'-[(4-methyl-1,2-phenylene)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino[2-(acetylamino)-5-methoxy-4,1-phenylene]azo]]bisnaphthalene-1,5-disulphonate is a high-performance, water-soluble reactive dye intermediate of significant industrial importance. This compound is valued for its ability to form strong covalent bonds with substrates, resulting in excellent color fastness and wash resistance. It is primarily utilized by manufacturers in the textile, specialty ink, and polymer coloration industries seeking durable and vibrant colorants.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-quality reactive dyes used in cotton, wool, and nylon dyeing and printing.
• Textile Coloration: Imparts bright, wash-fast colors to cellulosic and polyamide fibers in industrial textile processing.
• Inkjet Inks: Used in the formulation of specialty inks for digital textile printing, offering superior optical density and stability.
• Paper Dyeing: Employed in the production of colored paper and paperboard where high color strength is required.
• Leather Finishing: Applied in dyeing leather goods to achieve consistent and durable coloration.
• Research & Development: Serves as a critical building block in R&D for novel chromophores and functional dyes.
