Description

Trisodium 4-[[6-[[4-Chloro-6-(Methylphenylamino)-1,3,5-Triazin-2-Yl]Amino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]Toluene-2,5-Disulphonate is a high-purity, water-soluble anionic dye belonging to the reactive azo dye class, characterized by its triazine-based reactive group. This compound is engineered to deliver exceptional color fastness, brightness, and wash resistance when covalently bonded to cellulosic fibers. It is primarily required by manufacturers in the textile and specialty chemical industries seeking reliable, high-performance dyeing agents for demanding applications.

Application

• Primary Textile Dyeing: Used for dyeing cotton, viscose, and other cellulosic fibers, offering excellent fixation and reproducibility.
• Textile Printing: Applied in printing pastes for fabrics, providing sharp prints with good color yield.
• Leather Coloring: Employed in the dyeing of leather goods, ensuring deep, uniform coloration.
• Paper Coloring: Used as a colorant for specialty papers, including decorative and packaging grades.
• Ink Formulation: A key component in the manufacture of certain industrial inks requiring specific hue and stability.
• Research & Development: Serves as a standard or intermediate in chemical synthesis and dye research laboratories.
