Used in pharmaceutical research as a key intermediate in the synthesis of nicotinergic receptor ligands and neuroactive compounds. Shows potential in the development of treatments for neurological disorders such as Alzheimer's and Parkinson's due to its structural similarity to amino acids involved in neurotransmission. Also employed in the preparation of enzyme inhibitors and as a building block in the creation of biologically active molecules targeting central nervous system pathways. Its hydrochloride salt form enhances solubility and stability, making it suitable for in vitro and in vivo studies.
