Used as an intermediate in the synthesis of radiopaque contrast agents, particularly in the development of iodinated X-ray contrast media. Its structure supports high iodine content and water solubility when further functionalized, making it valuable for enhancing image clarity in diagnostic radiology. Also employed in the preparation of sulfonamide-based pharmaceuticals due to the sulfonamide group's biological activity. Suitable for use in coupling reactions and derivatization processes in medicinal chemistry.
