Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules that require iodinated heterocyclic structures. Its reactivity allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic frameworks. Commonly employed in medicinal chemistry for lead optimization due to its ability to enhance binding affinity and metabolic stability in drug candidates. Also utilized in the preparation of radiolabeled compounds for imaging and tracer studies.
