3-Bromo-2-iodopyridine is a key intermediate in the synthesis of complex heterocycles and active pharmaceutical ingredients (APIs). It is particularly valuable in palladium-catalyzed cross-coupling reactions to construct biaryl systems. Researchers also employ it in material science for developing organic electronic compounds. Its dual halogen functionality allows selective sequential functionalization.
