Used as a redox-active dye in electrochemical sensors due to its reversible oxidation-reduction behavior. Its quinone-imine structure enables electron transfer in biosensing platforms, particularly in detecting biomolecules like glucose and hydrogen peroxide. Also applied in dye-sensitized solar cells as a light-absorbing component, where its conjugated system enhances electron injection efficiency. Shows potential in anticancer research by intercalating into DNA and generating reactive oxygen species under light activation. Additionally, serves as a precursor in synthesizing anthraquinone-based pigments and functional polymers with conductive properties.
