Used as an organic redox mediator in electrochemical applications due to its stable quinone-hydroquinone transformation. Exhibits good electron transfer properties, making it suitable for use in dye-sensitized solar cells and organic-based batteries. Also employed in the synthesis of functional dyes and pigments, where its planar aromatic structure and hydrogen bonding capacity enhance color fastness and light absorption characteristics. Shows potential in analytical chemistry as a derivatization reagent for detecting biomolecules with redox activity.
