Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating targeted therapies. It is also employed in the preparation of bioactive molecules in medicinal chemistry research, where the presence of both chlorine and iodine enables further functionalization through cross-coupling reactions. Commonly utilized in the formation of potential antitumor and antiviral agents due to its heterocyclic framework and reactivity profile.
