Used in the synthesis of pharmaceutical compounds, particularly as a chiral building block for developing drugs targeting the central nervous system. It plays a role in creating inhibitors for enzymes like gamma-aminobutyric acid (GABA) transaminase, which is relevant in treating neurological disorders such as epilepsy and anxiety. Additionally, it is employed in research to study receptor interactions and neurotransmitter pathways, aiding in the development of novel therapeutic agents. Its hydrochloride form ensures stability and solubility, making it suitable for laboratory and industrial applications.
