Description

Disodium 4-(Acetylamino)-5-Hydroxy-6-(Phenylazo)Naphthalene-1,7-Disulphonate is a high-purity, water-soluble azo dye intermediate of significant industrial importance. This compound is valued for its role in synthesizing vibrant and stable colorants, particularly in applications requiring specific hue and fastness properties. It is a critical raw material for manufacturers in the textile dyeing, ink formulation, and specialty pigment industries seeking consistent quality and reliable supply.

Application

• Primary Intermediate for Azo Dyes: Serves as a key building block in the synthesis of acid dyes and direct dyes for textiles, especially polyamide (nylon) and protein fibers (wool, silk).
• Specialty Ink Production: Used in the formulation of high-performance inks for jet printing, packaging, and security applications.
• Pigment Manufacturing: Acts as a precursor in the production of lake pigments and other colorants for plastics and coatings.
• Laboratory & Research: Employed as a standard or reagent in chemical research, analytical method development, and photochemical studies.
• Biological Staining: Potential use in the development of histological stains for microscopy due to its specific chromophore structure.
