Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of central nervous system agents. It serves as a building block for gamma-aminobutyric acid (GABA) analogs, which are important in the development of drugs for neurological disorders such as epilepsy, neuropathic pain, and anxiety. Also utilized in research settings for the preparation of bioactive molecules and in the study of neurotransmitter pathways. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various chemical reactions and formulations.
