Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding and improved metabolic stability in drug candidates. Commonly employed in cross-coupling reactions to introduce functionalized pyridine moieties into target molecules. Also utilized in the preparation of radiolabeled analogs for positron emission tomography (PET) imaging due to the presence of iodine, enabling diagnostic applications in neurology and oncology.
