Description

Trisodium 7-[[2-[(Aminocarbonyl)Amino]-4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]Phenyl]Azo]Naphthalene-1,3,5-Trisulphonate is a high-purity, reactive dye intermediate belonging to the class of chlorotriazine-based azo compounds. Its core value lies in its ability to form stable covalent bonds with cellulosic fibers, making it an essential building block for producing high-performance, wash-fast reactive dyes. This chemical is primarily needed by manufacturers in the textile, leather, and specialty paper industries seeking to develop vibrant and durable colorants. Its specific molecular architecture provides excellent solubility and reactivity for advanced dye synthesis.

Application

• Primary Intermediate for Fiber-Reactive Dyes: Key starting material for synthesizing reactive dyes used on cotton, viscose, and other cellulose-based textiles.
• Leather Coloring Agent: Used in the production of dyes for achieving deep, uniform colors on leather goods with good fastness properties.
• Paper Dye Synthesis: Employed in manufacturing dyes for specialty papers requiring high color strength and stability.
• Research & Development: Serves as a precise chemical entity for R&D laboratories developing new chromophores and studying dye-fiber interactions.
• Textile Ink Formulation: A component in the synthesis of pigments and dyes for digital textile printing inks.
