Description

Trisodium 7-[[4-Chloro-6-[(3-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Methylamino]-4-Hydroxy-3-[(4-Methoxy-2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate is a high-purity, water-soluble reactive dye intermediate essential for creating vivid and wash-fast colors. Its molecular structure, featuring chlorotriazine and azo groups, provides excellent reactivity and binding affinity for cellulose fibers like cotton and viscose. This compound is a critical raw material for manufacturers of textile dyes, specialty inks, and colorants requiring superior color strength and durability.

Application

• Primary application in the synthesis of reactive dyes for the textile industry, particularly for dyeing and printing cotton, linen, and other cellulosic fibers.
• Used in the production of specialty inks, including inks for digital textile printing and security applications.
• Serves as a key intermediate for manufacturing high-performance pigments and colorants used in coatings and plastics.
• Employed in research and development laboratories for creating novel chromophoric systems and functional dyes.
• Potential use in the formulation of biological stains and diagnostic reagents due to its specific light-absorbing properties.
