Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for creating active pharmaceutical ingredients (APIs) due to the presence of both ester and aminomethyl functional groups, which allow for further chemical modifications. Commonly employed in the preparation of analgesics and neuromodulatory drugs. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction environments during drug manufacturing.
