Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of compounds requiring iodinated aromatic structures. Its aldehyde group allows for further functionalization through condensation or reduction reactions, making it valuable in building complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions due to the presence of the iodine atom, enabling the formation of carbon-carbon bonds in fine chemical synthesis. Also utilized in the preparation of bioactive molecules and potential drug candidates targeting neurological and inflammatory conditions.
