Used as an intermediate in the synthesis of pharmaceuticals, including local anesthetics and other bioactive compounds. It serves as a building block in the preparation of agrochemicals, dyes, and heterocyclic compounds such as quinolines via reactions like the Friedländer synthesis. Its aldehyde and amine functional groups enable versatile reactivity in condensation reactions and the formation of Schiff bases. Additionally, it is utilized in research for developing novel bioactive molecules, fluorescent probes, and materials with potential applications in biosensors and optoelectronics due to its aromatic structure and reactivity.
