Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its structure allows for selective binding in receptor assays, making it valuable in developing neuropharmacological agents. Commonly employed in radiolabeling studies due to the presence of iodine, enabling imaging and tracer applications in preclinical models. Also utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity of novel therapeutics.
