Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. 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 Negishi couplings to introduce the pyridine scaffold into drug candidates. Also utilized in agrochemical research for designing novel pesticides due to its halogenated structure, which enhances binding affinity and metabolic stability.
