Description

Disodium 9,10-Dihydro-9,10-Dioxoanthracene-1,7-Disulphonate is a high-purity, water-soluble anthraquinone derivative valued for its role as a key intermediate in the synthesis of specialty dyes and functional materials. Its disulphonate structure provides excellent solubility and reactivity, making it a critical building block for manufacturers requiring consistent quality and reliable supply. This compound is essential for producers of acid dyes, reactive dyes, and other colorants used in the textile, leather, and paper industries.

Application

• Primary Intermediate for Dye Synthesis: A crucial starting material for manufacturing high-value anthraquinone-based acid dyes and reactive dyes.
• Textile Dyeing: Used in the production of dyes for coloring nylon, wool, and silk, offering good light and wash fastness.
• Functional Colorants: Serves as a precursor for dyes used in ink-jet printing, leather finishing, and paper coloration.
• Chemical Research & Development: Employed as a standard or intermediate in organic synthesis and material science research.
• Specialty Chemical Manufacturing: Acts as a building block for creating more complex sulphonated aromatic compounds with specific industrial applications.
