Description

5-(Benzoylamino)-3-[[4-[[4-Chloro-6-[(4-Sulphophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-2-Sulphophenyl]Azo]-4-Hydroxynaphthalene-2,7-Disulphonic Acid is a high-purity, complex anionic dye intermediate belonging to the reactive dye class. Its core value lies in its ability to form strong covalent bonds with cellulose fibers, resulting in excellent wash and light fastness properties for textile applications. This compound is essential for manufacturers in the textile and specialty chemical industries seeking to produce vibrant, durable, and high-performance reactive dyes.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in cotton, viscose, and other cellulose fiber dyeing and printing.
• Textile Colorant Production: Imparts bright, strong shades (typically reds and blues) with superior fastness properties in commercial textile manufacturing.
• Specialty Chemical Synthesis: Used in research and development for creating novel chromophores and functional dyes with specific optical properties.
• Industrial Dye Formulation: A critical component in formulating dyes for applications requiring high stability and color strength.
