Used as a key intermediate in the synthesis of advanced organic compounds, particularly in pharmaceuticals and agrochemicals. Its multiple halogen atoms allow selective cross-coupling reactions, making it valuable in creating complex aromatic structures via Suzuki, Stille, or Ullmann reactions. Commonly employed in research and development of functional materials, including liquid crystals and organic semiconductors. Also utilized in the preparation of radiolabeled compounds for imaging and tracer studies due to the presence of iodine, which can be easily substituted or activated.
