Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where the pyridine ring serves as a core structure. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the introduction of various substituents for drug optimization. Also employed in the preparation of agrochemicals and functional materials due to its reactivity and structural properties. Commonly utilized in research settings for building complex heterocyclic systems.
