Used as an intermediate in organic synthesis, particularly in the preparation of functionalized aromatic compounds for pharmaceuticals and agrochemicals. Its iodine groups allow for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex molecules. The ethoxy groups provide solubility and influence electronic properties, making it useful in materials science, including the development of liquid crystals or organic semiconductors. Also employed in research settings for modifying molecular frameworks in medicinal chemistry.
