Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogenated pyridine structure, featuring bromine and iodine substituents, 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 aryl or amino groups. Also utilized in agrochemical research for designing novel active ingredients due to its reactivity and structural properties.
