Used as a key intermediate in the synthesis of non-ionic iodinated contrast agents for medical imaging, particularly in X-ray and computed tomography (CT) scans. Its high iodine content enhances radiopacity, allowing clear visualization of blood vessels, organs, and tissues during diagnostic procedures. The compound’s structure supports low osmolality and reduced toxicity in final contrast formulations, improving patient safety. It is modified chemically to produce agents like iopamidol, iohexol, and related compounds that are well-tolerated and effective in vascular and body cavity imaging.
