Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex drug candidates. Commonly employed in cross-coupling reactions and nucleophilic substitutions to introduce the pyridine moiety into larger molecular frameworks. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated aromatic core and reactive hydroxyl group.
