Used in the synthesis of heterocyclic compounds and dyes, particularly in the production of certain azo dyes and pigments due to its ability to undergo diazotization and coupling reactions. It serves as a building block in pharmaceuticals, especially in the development of drugs targeting central nervous system disorders. Also employed in the preparation of fluorescent probes and sensors, leveraging its photoluminescent properties when derivatized. Its structure supports metal chelation, making it useful in catalysis and analytical chemistry for detecting metal ions. Additionally, it finds use in polymer chemistry as a cross-linking agent or stabilizer in specialty resins.
