Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and heterocyclic compounds. Its structure allows for selective functionalization, making it valuable in cross-coupling reactions such as Suzuki or Heck reactions, where the iodine moiety serves as a reactive site. Commonly employed in the preparation of pyridine-based drug candidates, including kinase inhibitors and central nervous system agents. Also utilized in materials science for constructing complex organic frameworks due to its stability and reactivity profile.
