Description

Trisodium 2-[[6-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Methylamino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. This compound is valued for its ability to form strong covalent bonds with cellulosic fibers, resulting in excellent wash and light fastness properties. It is a critical raw material for manufacturers of high-performance textile dyes, colorants, and specialty pigments serving the global textile, paper, and leather industries.

Application

• Primary Intermediate for Reactive Dyes: Key building block in the synthesis of high-quality reactive dyes for cotton, viscose, and other cellulosic fibers.
• Textile Dyeing and Printing: Used to produce vibrant and durable dyes for exhaust, pad-batch, and continuous dyeing processes in the textile industry.
• Leather Coloring: Employed in the formulation of dyes for leather finishing, providing deep, stable coloration.
• Paper Coloring: Suitable for the production of colorants used in specialty paper and paperboard manufacturing.
• Ink Formulation: A component in the manufacture of certain industrial inks requiring specific color fastness and solubility.
• Research & Development: Serves as a standard or starting material in chemical R&D for novel chromophores and dye systems.
