Description

Disodium 5-[[4-[[2,6-Dihydroxy-3-[[2-Hydroxy-5-[(3-Sulphonatophenyl)Azo]Phenyl]Azo]Phenyl]Azo]Benzoyl]Amino]Salicylate is a high-purity, water-soluble azo dye intermediate known for its excellent chromophore properties. This compound is critical for synthesizing vibrant and stable dyes and pigments, particularly in applications requiring high color fastness and specific hue characteristics. It is primarily utilized by manufacturers in the textile, ink, and specialty coatings industries seeking to produce high-performance colorants.

Application

• Textile Dyeing: As a key intermediate for producing reactive and direct dyes for cotton, wool, and synthetic fibers.
• Ink Formulation: Used in the manufacture of high-quality printing inks for packaging and publications.
• Industrial Pigments: Serves as a precursor for organic pigments used in plastics, paints, and coatings.
• Leather Coloring: Employed in the synthesis of dyes for the leather tanning and finishing industry.
• Paper Coloring: Used in the production of dyes for specialty and decorative papers.
• Research & Development: Acts as a standard or building block in chemical research for novel chromophores and functional materials.
