Used primarily in pharmaceutical research as an intermediate in the synthesis of opioid receptor ligands. Its structure allows for selective modification to develop compounds with specific analgesic properties. Commonly employed in studies exploring pain management therapies, particularly in the development of potent analgesics with reduced side effect profiles. Also utilized in structure-activity relationship (SAR) studies to evaluate the impact of halogen substitution on benzazocine derivatives for enhanced binding affinity and metabolic stability.
