Used as a key intermediate in the synthesis of high-performance organic pigments and dyes, particularly in the production of phenazine pigments known for excellent light and weather fastness. Also employed in the development of electroactive materials and conductive polymers due to its ability to undergo reversible oxidation and complexation with metals. Finds niche applications in analytical chemistry as a derivatization reagent for carbonyl compounds and in the preparation of chemically modified electrodes for sensors. Its multiple amine groups enable cross-linking in polymer systems, enhancing thermal and mechanical stability of resulting materials.
