Description

Trisodium 5-[[4-Chloro-6-(Ethylphenylamino)-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(1-Sulphonato-2-Naphthyl)Azo]Naphthalene-2,7-Disulphonate is a high-purity, water-soluble anionic dye belonging to the reactive dye class, characterized by its complex triazine-based structure. This compound matters for its exceptional color strength and excellent substantivity, providing vibrant and durable coloration with strong covalent bonding to cellulosic fibers. Industrial manufacturers and R&D laboratories need this specialized chemical for advanced dyeing applications where superior wash and light fastness are critical performance requirements.

Application

• Primary Textile Dyeing: Used for dyeing cotton, viscose, and other cellulosic fibers, offering excellent wash fastness and brilliant shades.
• Leather Coloring: Applied in the leather industry for dyeing hides and skins, providing deep, uniform penetration and color.
• Paper Industry: Employed in the production of colored papers and specialty paper products requiring high color value.
• Ink Formulation: Serves as a key colorant in the formulation of inks for various printing applications.
• Research & Development: Utilized as a reference standard or intermediate in chemical synthesis and dye research laboratories.
• Biomolecule Staining: Potential application in histological staining or as a fluorescent probe in biochemical research due to its azo and aromatic structure.
