Description

6-Amino-5-[[4-[(5-Chloro-2,6-Difluoro-4-Pyrimidinyl)Amino]-2-Sulphophenyl]Azo]-4-Hydroxynaphthalene-2-Sulphonic Acid, Sodium Salt is a high-purity, water-soluble azo dye intermediate of significant commercial importance. Its complex molecular structure, featuring a pyrimidine ring and multiple sulphonic acid groups, makes it a critical precursor for synthesizing specialized dyes and pigments. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce high-performance colorants with specific fastness and solubility properties.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the synthesis of high-grade reactive dyes for cotton and other cellulosic fibers, providing excellent wash and light fastness.
• Specialty Pigment Synthesis: Used in the manufacture of complex organic pigments for high-performance inks, coatings, and plastics requiring specific color shades and stability.
• Textile Printing Inks: Serves as a crucial component in formulating advanced textile printing inks, particularly for digital and screen printing applications.
• Research & Development: Employed in chemical R&D laboratories for developing novel chromophores and studying structure-property relationships in dye chemistry.
• Functional Dye Production: Potential use in creating functional dyes for non-textile applications, such as sensors or imaging agents, due to its specific heterocyclic structure.
