Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for drugs targeting serotonin and dopamine receptors, including antipsychotics, antidepressants, and anxiolytics. Its structural features make it valuable in medicinal chemistry for optimizing receptor binding and pharmacokinetic properties. Also employed in research settings to design novel bioactive molecules and explore structure-activity relationships in piperazine-based compounds.
