Application

This iodinated proline derivative serves as a key intermediate in the synthesis of non-ionic X-ray contrast agents for medical imaging. Its high iodine content (approximately 60% by weight) provides excellent radiopacity while the modified proline moiety enhances water solubility and biocompatibility. Researchers utilize this compound to develop improved contrast media with reduced osmolality and nephrotoxicity compared to traditional ionic agents. The molecule’s stability under physiological conditions makes it particularly valuable for angiography and urography applications.
