Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows 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 agrochemicals and functional materials where halogenated pyridine derivatives are required.
