Description

2-Naphthalenesulfonic Acid, 7-(Benzoylamino)-4-Hydroxy-3-4-(4-Sulfophenyl)Azophenylazo-, Compd. With 2,2,2-Nitrilotrisethanol (1:2) is a high-purity, complex azo dye intermediate and colorant salt. This compound matters for its role in producing vivid and stable colors, particularly in demanding industrial applications where lightfastness and chemical resistance are critical. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries seeking consistent and high-performance pigments.

Application

• Textile Dyeing and Printing: As a key intermediate for synthesizing high-grade, wash-fast azo dyes for natural and synthetic fibers.
• Industrial Ink Formulation: Used in the production of pigments for printing inks, including packaging and security inks, where color intensity and stability are paramount.
• Specialty Coatings and Paints: Imparts durable coloration to industrial paints, automotive finishes, and other coating systems requiring UV and chemical resistance.
• Paper Coloring: Employed in the manufacture of colored papers and paper products requiring specific hue and brightness standards.
• Plastics and Polymers: Acts as a colorant masterbatch component for coloring various plastic resins during processing.
• Research and Development: Serves as a precise chemical reagent in R&D laboratories for developing new colorants and studying dye chemistry.
