Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of bioactive molecules and central nervous system agents. Its piperazine core with defined stereochemistry makes it valuable for creating selective receptor ligands. The chloromethyl group allows for further functionalization, enabling coupling reactions to attach the scaffold to other molecular frameworks. Commonly employed in medicinal chemistry for structure-activity relationship studies and in the preparation of protease inhibitors or GPCR-targeted compounds.
