Description

Trisodium 1-Amino-4-[[4-[[4-Chloro-6-[(2-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-3-Sulphonatophenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate is a high-purity, water-soluble reactive dye intermediate of significant industrial importance. Its core value lies in its ability to form covalent bonds with textile fibers, providing exceptional color fastness and wash durability. This compound is essential for manufacturers of high-performance reactive dyes targeting the textile, leather, and specialty paper industries, where vibrant and stable coloration is a critical requirement.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes for cotton, viscose, and other cellulosic fibers.
• Key component in the production of dyes for leather finishing, offering deep penetration and uniform color.
• Used in manufacturing colorants for specialty papers, including decorative and security papers.
• Potential intermediate for inkjet printing inks requiring high color strength and stability.
• Research and development of novel functional dyes for non-textile applications.
• Starting material for dyes used in the coloration of wood stains and other natural materials.
