Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of gamma-aminobutyric acid (GABA) analogs. It serves in the development of central nervous system agents, including drugs for treating neuropathic pain, epilepsy, and anxiety disorders. Also employed in research settings to study neurotransmitter pathways and to create novel bioactive molecules. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in both laboratory and industrial-scale reactions.
