Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized aromatic compounds. Its dual halogen functionality allows for selective cross-coupling reactions, enabling the construction of complex molecules in medicinal chemistry. Commonly employed in the development of radiolabeled compounds for imaging studies due to the presence of iodine, which can be easily substituted with radioactive isotopes. Also utilized in the synthesis of liquid crystals and conjugated polymers for electronic materials.
