Description

Disodium 5-[[5-[[4-Chloro-6-Isopropoxy-1,3,5-Triazin-2-Yl]Amino]-2-Sulphonatophenyl]Azo]-1-Ethyl-1,2-Dihydro-6-Hydroxy-4-Methyl-2-Oxopyridine-3-Methanesulphonate is a high-performance, water-soluble reactive dye intermediate, specifically engineered for the synthesis of brilliant and wash-fast colorants. Its molecular structure, featuring a reactive chlorotriazine group and multiple sulphonate moieties, provides exceptional reactivity with cellulose fibers and excellent solubility in aqueous systems. This compound is essential for manufacturers of reactive dyes targeting the textile, leather, and specialty paper industries, where consistent color strength and superior fastness properties are critical.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in cotton, viscose, and other cellulose fiber dyeing and printing.
• Textile Industry: Enables the production of dyes with excellent wash-fastness, light-fastness, and brilliant shades for apparel and home textiles.
• Leather Coloring: Used in the formulation of dyes for leather finishing, providing vibrant and durable colors.
• Paper Dyeing: Suitable for the coloration of specialty papers where high color value and stability are required.
• Research & Development: Serves as a crucial reference standard and starting material for developing novel chromophores and dye systems in chemical R&D laboratories.
• Ink Formulation: Potential use in the development of specialized inks for jet printing and other applications requiring water-soluble colorants.
