Used as a key intermediate in the synthesis of iodinated X-ray contrast media, particularly non-ionic contrast agents used in medical imaging. Its structure allows for high radiopacity while maintaining water solubility and biocompatibility when further processed. Commonly found in formulations for angiography, urography, and computed tomography (CT) scans due to its ability to enhance image clarity by effectively absorbing X-rays. The compound’s ester and amino groups enable chemical modifications that reduce toxicity and improve patient tolerance.
