Used primarily 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 production of antipsychotic and antidepressant drugs due to its structural similarity to piperazine-based neurotransmitter modulators. Its derivatives are explored for activity at serotonin, dopamine, and histamine receptors. Also utilized in research settings for the design of novel receptor ligands and in medicinal chemistry for structure-activity relationship (SAR) studies.
