Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its structure supports the creation of compounds with analgesic, antidepressant, or anti-anxiety effects. Commonly employed in medicinal chemistry for modifying pharmacokinetic properties such as bioavailability and metabolic stability. Also utilized in the preparation of selective receptor ligands, including those targeting opioid and serotonin receptors. Valuable in research settings for constructing novel heterocyclic systems in drug discovery.
