Description

Hexasodium 4-Amino-3,6-Bis[[5-[[4-Chloro-6-[(3-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-2-Sulphonatophenyl]Azo]-5-Hydroxynaphthalene-2,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. This compound is valued for its role in synthesizing brilliant and wash-fast dyes, particularly for cellulosic fibers like cotton and viscose. It is a critical raw material for manufacturers in the textile, ink, and specialty colorant industries seeking to produce high-performance, vivid shades of blue and green.

Application

• Primary use as a key intermediate in the synthesis of reactive dyes for cotton, linen, and other cellulosic textiles.
• Manufacture of high-quality fiber-reactive dyes known for excellent wash-fastness and brightness.
• Production of dyes for inkjet printing inks, especially for textile and wide-format printing.
• Used in the formulation of leather dyes and paper colorants.
• Potential applications in the research and development of functional dyes for optical or sensor technologies.
