Description

1,5-Naphthalenedisulfonic acid, 2-8-amino-7-5-4-chloro-6-3-2-(sulfooxy)ethylsulfonylphenylamino-1,3,5-triazin-2-ylamino-2-sulfophenylazo-1-hydroxy-3,6-disulfo-2-naphthalenylazo-, hexasodium salt is a high-purity, water-soluble anionic dye intermediate and specialty chemical. This compound is valued for its exceptional chromophore properties and reactivity, making it a critical building block for synthesizing complex colorants. It is primarily sought by manufacturers in the textile, ink, and specialty polymer industries for producing high-performance dyes and functional materials.

Application

• Primary Intermediate for Reactive Dyes: Key precursor in the synthesis of high-grade reactive dyes for cotton and cellulose fiber dyeing and printing.
• Specialty Ink Formulations: Used in manufacturing pigments for inks requiring specific solubility, color fastness, and stability, such as in jet printing inks.
• Functional Polymer Additive: Acts as a monomer or modifier in the production of polymers where ionic character, color, or UV-absorbing properties are desired.
• Analytical Chemistry Reagent: Serves as a complexometric agent or a chromogenic substrate in specific diagnostic and analytical applications.
• Research & Development: Utilized in chemical R&D for developing new chromophores, sensors, and advanced organic materials.
