Application

3,4-Dibromopyridine serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and specialty chemicals. It is widely used in palladium-catalyzed cross-coupling reactions to construct complex heterocycles. Researchers employ it in the development of kinase inhibitors and other bioactive molecules. Its bromine substituents also facilitate the creation of pyridine-based ligands for catalysis.
