2,7-Anthraquinone Disulfonic Acid
2,7-Anthraquinone disulfonic acid (CAS 84-49-1) is a disulfonated anthraquinone derivative with formula C₁₄H₈O₈S₂ and MW 368.34. The two strongly hydrophilic sulfonic acid groups on the aromatic core confer exceptional water solubility, enabling its use in aqueous reaction environments rather than traditional organic solvent systems.
• Dye and pigment manufacturing: anionic character and fabric affinity for textile applications.
• Redox mediator: aqueous catalytic systems, bleaching and environmental remediation.
• Pulp and paper processing: investigated as pulping additives for delignification.
• Laboratory and industrial research: electron-transfer kinetics, redox flow batteries and functionalized polycyclic aromatic compounds.
