Used in the synthesis of pharmaceutical compounds, particularly as an intermediate in the production of drugs targeting the central nervous system. It plays a role in the development of antipsychotic and antidepressant medications due to its piperazine moiety, which is a common structural feature in such drugs. Additionally, it is utilized in organic chemistry research for the preparation of complex molecules, aiding in the study of biochemical pathways and drug-receptor interactions. Its tert-butyl ester group provides stability and ease of handling during synthetic processes.
