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 active pharmaceutical ingredients (APIs) due to its functional groups that allow for further chemical modifications. Commonly employed in the production of antidepressants and anxiolytic drugs, where the nitrile and amine functionalities enable key structural transformations. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in controlled reaction environments during drug manufacturing.
