Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where halogenated pyridines serve as building blocks for cross-coupling reactions. Its dual halogen functionality allows selective substitution, enabling the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in palladium-catalyzed reactions such as Suzuki or Heck couplings to form carbon-carbon bonds in drug discovery and agrochemical research. Also utilized in the preparation of kinase inhibitors and other targeted therapies in medicinal chemistry.
