Description

5-[[4-chloro-6-[(3-sulphophenyl)amino]-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]naphthalene-2,7-disulphonic acid, sodium salt is a high-purity, reactive dye intermediate essential for producing brilliant and wash-fast colors. This compound matters for manufacturers seeking consistent, high-performance chromophores to meet stringent quality standards in demanding applications. It is primarily needed by producers of reactive dyes for the textile industry, as well as developers of specialized colorants for inks and other advanced materials.

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: Enables the manufacture of dyes with excellent color yield, brightness, and superior wet-fastness properties.
• Specialty Ink Formulations: Used in the development of advanced inkjet and other specialty inks requiring specific color characteristics and stability.
• Research & Development: Serves as a critical reagent in chemical R&D for creating novel chromophores and functional dyes.
• Industrial Colorants: Potential use in the synthesis of colorants for paper, leather, and other industrial applications demanding color fidelity.
