Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules due to the presence of both iodine and heterocyclic thiophene ring, enabling cross-coupling reactions like Suzuki or Heck reactions. Applied in the development of functional materials, including organic semiconductors and electronic devices, where aryl iodides act as precursors for conjugated systems. Also explored in medicinal chemistry for radiolabeling studies owing to the iodine atom, which can be replaced with radioactive isotopes for imaging or therapeutic purposes.
