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 bromo functional group allows for further modification through cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of complex molecules. Commonly employed in agrochemicals for the production of herbicides and insecticides due to its stability and reactivity. Also utilized in research and development of new functional materials and ligands for catalysis.
