Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves in the production of certain antipsychotic and antidepressant drugs due to its structural compatibility with bioactive molecules. Also employed in research settings for the preparation of novel piperazine derivatives for biological screening. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various reaction conditions and formulations.
