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 functionalization, making it valuable in medicinal chemistry for creating drug candidates targeting inflammatory diseases and certain cancers. Also employed in agrochemical research for designing novel pesticides due to its halogenated pyridine core, which enhances bioavailability and binding affinity. Commonly utilized in organic synthesis to build complex heterocyclic systems through cross-coupling and nucleophilic substitution reactions.
