Description

Trisodium 2-[4-[[6-[[[[4-(Acetamido)Phenyl]Amino]Carbonyl]Amino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]-3-Sulphonatophenyl]-6-Methylbenzothiazole-7-Sulphonate is a high-purity, water-soluble anionic dye belonging to the benzothiazole azo class, identified by CAS No. 6417-31-8. This compound is engineered to deliver exceptional color strength, lightfastness, and thermal stability in demanding industrial applications. It is a critical component for manufacturers in the textile, leather, paper, and specialty ink industries who require reliable and consistent colorants for their production processes.

Application

• Textile Dyeing: Primary application for dyeing cotton, wool, silk, and nylon fibers, offering excellent wash and light fastness.
• Leather Finishing: Used for coloring finished leather goods, providing rich, uniform shades with good adhesion.
• Paper Coloration: Employed in the production of colored papers, including specialty packaging and decorative papers.
• Ink Manufacturing: A key pigment for formulating inks used in flexographic, gravure, and inkjet printing.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its specific chromogenic properties.
• Industrial Markers: Suitable for use in non-food contact industrial markers and colorants.
