Description

Trisodium 4-[(1-Hydroxy-4-Sulphonato-2-Naphthyl)Azo]-5,5'-Dimethyl-4'-[[4-[[(4-Methylphenyl)Sulphonyl]Oxy]Phenyl]Azo][1,1'-Biphenyl]-2,2'-Disulphonate is a high-purity, water-soluble azo dye intermediate with a complex, multi-sulfonated structure. This compound is valued for its ability to impart specific color properties and act as a key building block in the synthesis of advanced dyes and pigments. It is primarily sought by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants with excellent fastness and solubility properties.

Application

• Primary Intermediate for Reactive Dyes: A critical precursor in the synthesis of high-quality reactive dyes for cotton and cellulose fiber dyeing and printing.
• Specialty Pigment Manufacturing: Used in the production of high-performance organic pigments for inks, coatings, and plastics that require specific hue and stability.
• Functional Dye Synthesis: Serves as a key component in creating functional dyes for non-textile applications, including paper coloring and leather finishing.
• Research & Development: Employed in chemical R&D laboratories for developing novel chromophores and studying azo dye chemistry and properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity. Keep away from incompatible materials such as strong oxidizing agents.
