Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce the pyridine moiety into drug candidates. Also utilized in the preparation of radiolabeled compounds for positron emission tomography (PET) imaging due to the presence of iodine, which can be substituted with radioactive isotopes.
