Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders. Its structure supports the creation of more complex molecules with potential antipsychotic, antidepressant, or anxiolytic activity. Commonly employed in medicinal chemistry research for modifying pharmacokinetic properties such as bioavailability and metabolic stability. Also utilized in the preparation of novel piperazine derivatives for structure-activity relationship (SAR) studies.
