Description

Tetrasodium 5-[[4-Chloro-6-[(4-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(2-Sulphonatophenyl)Azo]Naphthalene-2,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its core value lies in its ability to form covalent bonds with cellulose fibers, providing exceptional color fastness and wash resistance in textile applications. This compound is essential for manufacturers of reactive dyes, particularly those serving the textile, leather, and specialty paper industries, where vibrant and durable coloration is a critical requirement.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the synthesis of high-performance reactive dyes for cotton, viscose, and other cellulosic fibers.
• Textile Industry: Used in dyeing and printing processes to achieve brilliant shades of red and related hues with excellent wet fastness properties.
• Leather Coloring: Employed in the production of dyes for coloring leather goods, offering good penetration and color stability.
• Paper Industry: Utilized in the manufacture of specialty colored papers where high color strength and stability are required.
• Research & Development: Acts as a critical reagent in chemical R&D for developing new dye molecules and studying azo-triazine chemistry.
• Ink Formulations: Potential use in the formulation of specialty inks where specific color properties and substrate adhesion are needed.
