Used as a key intermediate in the synthesis of thienopyridine-based pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of bioactive molecules with high receptor selectivity. Commonly employed in medicinal chemistry for constructing heterocyclic scaffolds that enhance metabolic stability and binding affinity. Also utilized in research settings to develop novel CNS-active agents due to its ability to cross the blood-brain barrier. The iodine moiety allows for further functionalization via cross-coupling reactions, making it valuable in structure-activity relationship (SAR) studies.
