Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that require piperazine-based structures. Its protected tert-butyl ester group allows for selective reactions in multi-step organic syntheses, making it valuable in drug discovery and development. Commonly employed in the preparation of neuroprotective agents, cognitive enhancers, and certain antipsychotic drugs. Also utilized in research settings for modifying peptide-like structures due to its stability and reactivity profile.
