Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its chiral structure makes it valuable in creating enantiomerically pure compounds, which are critical for drugs with high specificity and reduced side effects. Commonly applied in research settings for the preparation of neuroactive agents, including those targeting epilepsy, anxiety, and other neurological disorders. Also utilized in the production of peptide mimetics due to its stable piperazinone backbone, which can enhance metabolic stability and bioavailability in drug candidates.
