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—bromine, chloromethyl, and methoxy—allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex pyridine-based structures. Commonly employed in Suzuki, Negishi, or Buchwald-Hartwig reactions to introduce the pyridine core into target molecules. Also utilized in agrochemical research for designing novel pesticides due to its reactivity and structural features.
