Description

Trisodium 7-[[4-Chloro-6-[n-(Sulphonatomethyl)Anilino]-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(o-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate 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, leather, and specialty ink industries seeking to produce high-performance colorants with excellent stability and environmental profile.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the synthesis of high-quality reactive dyes for textile printing and dyeing.
• Cotton and Cellulosic Fiber Dyeing: Used to produce dyes that form covalent bonds with cotton, linen, and rayon, resulting in superior wash and light fastness.
• Leather Coloring: Employed in the manufacture of dyes for coloring leather goods, providing vibrant and durable shades.
• Paper and Specialty Ink Production: Finds application in creating colorants for high-grade paper and certain types of inks requiring specific solubility and hue.
• Research & Development: Utilized in chemical R&D labs for developing novel dye structures and studying azo-triazine chemistry.
