Description

Disodium 6-[[2-[2-(Cyclohexylamino)Phenoxy]Phenyl]Azo]-4-[[(2,4-Dichlorophenoxy)Acetyl]Amino]-5-Hydroxynaphthalene-1,7-Disulphonate is a high-purity, complex synthetic organic dye intermediate characterized by its azo and naphthalene disulphonate structure. This compound matters for its role as a key precursor in the synthesis of specialized dyes and pigments requiring specific color fastness and chemical stability. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries for producing high-performance colorants.

Application

• Primary intermediate for synthesizing high-value azo dyes and pigments.
• Manufacture of specialized colorants for textile fibers, including nylon and polyester.
• Production of pigments for industrial inks, including printing and packaging inks.
• Key component in the formulation of functional dyes for non-textile applications.
• Research and development of novel optical materials and sensors.
• Potential use in the synthesis of liquid crystal display (LCD) color filters.
