Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of targeted cancer therapies. Its structure supports the design of compounds with high selectivity for specific enzyme targets. The iodine substituent enables versatile reactions, such as palladium-catalyzed cross-couplings, allowing the formation of carbon-carbon or carbon-nitrogen bonds for further elaboration of drug molecules. Also employed in the preparation of radiolabeled derivatives for use in positron emission tomography (PET) imaging due to the presence of iodine, enabling non-invasive tracking in biological systems. Additionally, it serves as a building block in the discovery of new bioactive molecules within medicinal chemistry programs.
