Used as a redox-active compound in electrochemical sensors and biosensors due to its strong electron-donating properties. Its multiple amine groups enhance solubility in aqueous systems and facilitate immobilization on electrode surfaces. Employed in the development of conductive inks and dyes for organic electronics, including dye-sensitized solar cells and molecular electronics. Also investigated for use in antimicrobial coatings and as a precursor in the synthesis of functionalized phenazine derivatives with potential biological activity.
