Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It serves as a building block in the creation of serotonin receptor modulators and antipsychotic drugs due to its structural affinity for neurotransmitter receptors. Its piperazine-biphenyl scaffold enhances blood-brain barrier penetration, making it valuable in designing bioactive molecules for neurological disorders. Also employed in research settings to explore structure-activity relationships in receptor binding studies.
