Description

1 5-Anthraquinonedisulfonic Acid is a high-purity, water-soluble disulfonic acid derivative of anthraquinone, serving as a critical intermediate in the synthesis of dyes and pigments. Its primary commercial value lies in its role as a precursor for manufacturing vibrant and stable colorants, particularly acid dyes and reactive dyes for textiles. This compound is essential for suppliers and manufacturers in the dye and pigment, fine chemical synthesis, and research and development sectors seeking reliable, high-quality intermediates.

Application

• Dye & Pigment Intermediate: A key precursor in the synthesis of acid dyes, reactive dyes, and other anthraquinone-based colorants for textiles, leather, and paper.
• Chemical Synthesis: Used as a building block or sulfonating agent in the production of more complex specialty chemicals and pharmaceutical intermediates.
• Catalyst & Reagent: Employed in certain organic synthesis reactions and as a reagent in analytical chemistry applications.
• Research & Development: Serves as a standard or starting material in laboratory-scale research for developing new dyes, functional materials, or chemical processes.
