Used in pharmaceutical synthesis as an intermediate for developing bioactive compounds, particularly in the production of central nervous system agents and receptor modulators. Its structure supports the creation of nitrogen-containing heterocycles, which are common in drugs targeting neurological disorders. Also employed in research settings to design novel quinoline-based molecules with potential anticonvulsant, antidepressant, or antipsychotic activity. The hydrochloride salt form enhances solubility and stability, making it suitable for use in polar reaction environments and purification processes.
