Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) requiring piperazine moieties. Its structure supports the creation of compounds with central nervous system activity, including potential antipsychotic or antidepressant agents. The ethyl ester group allows for further chemical modifications, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in research settings to design novel bioactive molecules due to its conformational flexibility and solubility properties.
