Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where the iodo group allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. Its structure supports the construction of complex pyridine-based molecules found in bioactive compounds. Commonly employed in research and development for agrochemicals and medicinal chemistry due to its reactivity and ability to serve as a building block in heterocyclic chemistry.
