This compound is the sodium salt of anthraquinone-2-sulfonic acid — an anthraquinone core (three fused six-membered rings with two ketone groups) carrying a water-solubilizing sulfonate group. Anthraquinone’s reversible two-electron redox chemistry is what makes this structural family valuable for energy-storage applications.
This compound is manufactured into organic redox-flow battery electrolytes, where anthraquinone sulfonates serve as water-soluble, reversibly reducible/oxidizable active species — an active area of grid-scale energy-storage materials development. It’s also used in electroanalytical and UV-detection method development.
