Description

4-[(3-chloro-2-methylphenyl)azo]-N-[4-[[[4-[[[4-[(3-chloro-2-methylphenyl)azo]-3-hydroxy-2-naphthyl]carbonyl]amino]phenyl]amino]carbonyl]phenyl]-3-hydroxynaphthalene-2-carboxamide is a high-purity, complex bis-azo pigment intermediate. This compound is valued for its ability to impart excellent color strength, thermal stability, and lightfastness in demanding applications. It is primarily required by manufacturers in the pigments, dyes, and specialty coatings industries for producing high-performance colorants.

Application

• High-Performance Organic Pigments: A key intermediate for synthesizing high-grade azo pigments, particularly yellows, oranges, and reds.
• Plastics and Masterbatch Coloring: Used in the production of pigments for coloring engineering plastics, PVC, and polyolefins requiring excellent dispersion and heat resistance.
• Industrial and Automotive Coatings: Imparts durable coloration in coatings that demand superior weatherability and chemical resistance.
• Specialty Inks: Formulation of high-quality inks for packaging, security printing, and other applications requiring vibrant, stable colors.
• Synthetic Fibers: Production of pigments for mass coloration (dope dyeing) of synthetic fibers like polyester and nylon.
