Description

2-[[4-[[4-[[4-Chloro-6-[(2,5-Disulphophenyl)Amino]-1,3,5-Triazin-2-Yl]Methylamino]Phenyl]Azo]-5-Methoxy-2-Methylphenyl]Azo]Benzene-1,4-Disulphonic Acid is a high-performance, reactive dye intermediate belonging to the class of azo dyes containing a chlorotriazine reactive group. This compound is critically important for synthesizing vibrant, wash-fast, and light-fast dyes used in demanding textile applications. It is primarily required by manufacturers of reactive dyes for the coloration of cellulosic fibers like cotton, viscose, and linen.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing high-quality reactive dyes used in textile printing and dyeing.
• Cellulosic Fiber Dyeing: Specifically engineered for dyeing cotton, rayon, linen, and other natural cellulosic materials with excellent fastness properties.
• Textile Industry: Used in exhaust dyeing, continuous dyeing, and printing processes for apparel, home textiles, and industrial fabrics.
• Specialty Colorant Synthesis: Serves as a precursor for creating specific, complex shade ranges, particularly bright and deep colors.
• Research & Development: Utilized in R&D laboratories for developing new dye formulations and studying dye-fiber interactions.
