Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to the piperazine ring and substituted phenyl group, which are common motifs in neuroactive drugs. The Boc-protected amine allows for selective deprotection and further functionalization in multi-step organic syntheses. Commonly employed in medicinal chemistry for constructing drug candidates targeting serotonin and dopamine receptors. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies.
