Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Its structure allows functionalization at multiple sites, making it valuable in constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form biaryl or styrene derivatives. Also applied in the development of bioactive molecules due to the presence of the iodinated thiophene core, which can enhance binding affinity and metabolic stability in drug candidates.
