Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for creating piperidine-based compounds that exhibit biological activity, such as receptor agonists or antagonists. Commonly employed in medicinal chemistry for modifying drug candidates to enhance potency, selectivity, or metabolic stability. Also utilized in the preparation of radiolabeled derivatives for receptor binding studies. Its iodine functionality allows for further chemical modifications via cross-coupling reactions, making it valuable in structure-activity relationship (SAR) research.
