Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its structural features make it valuable in creating compounds with potential antipsychotic, antidepressant, or anxiolytic activity. Commonly employed in medicinal chemistry research for designing new piperazine-based drug candidates. Also utilized in the preparation of ligands for receptor binding studies, especially targeting serotonin and dopamine receptors. Its lipophilic tert-butyl group enhances blood-brain barrier penetration, making it favorable for neuropharmacological applications.
