Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure allows for selective modification to create bioactive molecules, making it valuable in medicinal chemistry for designing dopamine or serotonin receptor modulators. Commonly employed in research settings to develop potential antipsychotic, antidepressant, or anti-anxiety drugs. Also utilized in the preparation of novel piperazine derivatives for structure-activity relationship (SAR) studies.
