Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders. Its structure supports the creation of highly selective receptor ligands, making it valuable in drug discovery for psychiatric and neurological conditions. Also employed in the preparation of novel piperazine derivatives with potential antimicrobial and anticancer activities. Commonly utilized in research settings for structure-activity relationship (SAR) studies due to its rigid cyclobutyl group that influences molecular conformation and bioavailability.
