Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves as a building block for compounds exhibiting antipsychotic, antidepressant, or cognitive-enhancing properties. Its structure supports the design of molecules that can cross the blood-brain barrier, making it valuable in neuropharmacology research. Also employed in the preparation of novel piperazine derivatives for structure-activity relationship (SAR) studies during drug discovery.
