Used primarily as an intermediate in organic synthesis, particularly in the preparation of indoles and other heterocyclic compounds through palladium-catalyzed or copper-mediated cyclization reactions. It serves as a versatile building block in pharmaceutical and agrochemical research due to the reactivity of the iodine atom, which allows for cross-coupling reactions such as Suzuki or Heck couplings. Its acetate group can also be hydrolyzed or transformed, enabling further functionalization. Commonly employed in the development of bioactive molecules and complex polycyclic structures.
