Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its piperazine core with defined stereochemistry makes it valuable for constructing drug candidates with high selectivity and improved metabolic stability. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in optimizing dopamine or serotonin receptor modulators. Also utilized in the preparation of analogs for biological screening in early-stage drug discovery.
