Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) involving piperazine derivatives. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in creating compounds with central nervous system activity. Commonly employed in research settings for designing novel drugs targeting neurological disorders, including antidepressants and antipsychotics. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical stability and solubility properties.
