Used in organic synthesis as an intermediate for pharmaceutical compounds, particularly in the development of kinase inhibitors. Exhibits utility in medicinal chemistry for constructing bioactive molecules due to the presence of reactive iodine and sulfonamide functional groups. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds in drug discovery pathways. Also serves as a building block in the preparation of heterocyclic compounds with potential antitumor and anti-inflammatory activities.
