Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) drugs. Its structure supports the creation of compounds with neuroactive properties, including potential antipsychotic and cognitive-enhancing agents. Commonly employed in medicinal chemistry for modifying piperazine-based molecules to improve bioavailability and receptor selectivity. Also utilized in the preparation of peptide mimetics and enzyme inhibitors due to its stable amide and aromatic functionalities.
