Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its functional groups allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in Suzuki and Buchwald–Hartwig reactions to form carbon–carbon and carbon–nitrogen bonds. Also utilized in the preparation of potential agrochemicals and diagnostic agents due to its halogenated pyridine scaffold.
