Description

Trisodium 1-Amino-4-[3-[[4-Chloro-6-(3-Sulphonatoanilino)-1,3,5-Triazin-2-Yl]Amino]-4-Sulphonatoanilino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate is a high-purity, water-soluble anthraquinone-based dye intermediate. This compound is valued for its role in synthesizing high-performance, reactive dyes that offer excellent color fastness and brightness. It is primarily needed by manufacturers in the textile, leather, and specialty ink industries for producing vibrant and durable colorants.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-quality reactive dyes used in cotton, wool, and nylon dyeing and printing.
• Textile Industry: For producing dyes that provide excellent wash and light fastness on cellulosic and polyamide fibers.
• Leather Coloring: Used in the formulation of dyes for leather finishing, offering deep, uniform shades.
• Inkjet Inks: Serves as a precursor for pigments in high-performance digital textile and industrial inks.
• Paper Dyeing: Employed in the production of dyes for specialty paper and packaging materials.
• Research & Development: Used as a standard or building block in chemical research for developing new chromophores and functional dyes.
