Description

Disodium 7-[4-Chloro-6-(n-Ethyl-o-Toluidino)-1,3,5-Triazin-2-Ylamino]-4-Hydroxy-3-(4-Methoxy-2-Sulfonatophenylazo)-2-Naphthalenesulfonate is a high-performance, water-soluble reactive dye intermediate. This compound is critical for imparting vibrant and wash-fast colors to cellulose fibers like cotton and viscose. It is primarily needed by manufacturers in the textile dyeing and printing industries, as well as by specialty chemical producers developing advanced colorants for technical applications.

Application

• Primary Intermediate for Reactive Dyes: Key building block in the synthesis of high-quality reactive dyes for cotton, linen, and other cellulosic fibers.
• Textile Dyeing: Used in exhaust and continuous dyeing processes to achieve brilliant shades with excellent fastness properties.
• Textile Printing: Employed in the formulation of printing inks and pastes for textile printing applications.
• Specialty Colorant Production: Serves as a precursor for creating specialized dyes and pigments for paper, leather, and other substrates.
• Research & Development: Utilized in R&D laboratories for developing new dye molecules and studying dye-fiber interactions.
