Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its functional groups allow for selective cross-coupling reactions, making it valuable in constructing complex heterocyclic compounds for drug discovery. Commonly employed in agrochemical research to build active ingredients in crop protection agents. Also utilized in the preparation of fluorescent probes and dyes due to its ability to undergo condensation reactions that form conjugated systems. Its reactivity supports its role in multistep organic syntheses where halogenated pyridine scaffolds are required.
