Used as a key intermediate in the synthesis of X-ray contrast agents, particularly non-ionic iodinated contrast media. Its high iodine content provides excellent radiopacity, making it effective for enhancing image clarity in diagnostic imaging such as CT scans and angiography. The compound's structure allows for further chemical modification to improve water solubility and biocompatibility, which helps reduce toxicity and improve patient tolerance. It is also explored in the development of contrast agents with lower osmolality and fewer side effects.
