Description

4-[[4-chloro-6-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-5-hydroxy-6-[(2-sulphophenyl)azo]naphthalene-1,7-disulphonic acid, sodium salt is a high-performance, water-soluble reactive dye intermediate of significant industrial importance. Its complex molecular structure, featuring multiple sulphonic acid groups and a reactive triazine moiety, provides excellent binding affinity and chromogenic properties for synthetic fibers. This compound is essential for manufacturers requiring vivid, wash-fast colors in textiles and advanced materials. Its primary utility lies in the synthesis of specialized dyes for the global textile and specialty chemical industries.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes, particularly for cotton, viscose, and other cellulosic fibers.
• Used in the production of dyes requiring exceptional wet fastness and brilliant shades, such as brilliant blues and turquoises.
• Key component in manufacturing dyes for industrial inkjet inks and digital textile printing applications.
• Employed in research and development for creating novel functional dyes with specific optical or chemical properties.
• Potential use in the coloration of paper and specialty papers where high color strength is required.
• Serves as a starting material for dyes used in leather finishing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and performance. Keep away from incompatible materials such as strong oxidizing agents.
