Description

5-[[4-Chloro-6-[(o-Tolyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(2-Sulphophenyl)Azo]Naphthalene-2,7-Disulphonic Acid is a high-performance, water-soluble anionic dye belonging to the reactive dye class, distinguished by its triazine and azo chromophore structure. This compound is engineered to deliver exceptional color fastness, brilliant shade, and strong covalent bonding to cellulosic fibers, making it a critical component for demanding coloration processes. It is primarily required by manufacturers in the textile, leather, and specialty paper industries seeking reliable and vibrant dyeing solutions.

Application

• Reactive Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, viscose, rayon, and linen with high wash and light fastness.
• Leather Coloration: Used for dyeing leather goods, providing deep, uniform penetration and color stability.
• Paper Dyeing: Imparts vibrant colors to specialty papers, including decorative and security papers.
• Ink Formulation: Serves as a colorant in the production of inks for various industrial printing applications.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its specific chromogenic properties.
• Research & Development: Used as a key intermediate or reference standard in chemical research for developing new dyes and pigments.
