Used primarily in the synthesis of pharmaceutical compounds, particularly those targeting neurological disorders. It serves as a precursor in the production of drugs that modulate neurotransmitter activity, such as GABA analogs, which are effective in treating conditions like epilepsy, anxiety, and chronic pain. Additionally, it finds application in research settings for studying the biochemical pathways involving amino acid derivatives and their impact on cellular functions. Its hydrochloride form enhances solubility, making it suitable for use in various experimental and formulation processes.
