Used in the synthesis of X-ray contrast agents due to its high iodine content, which enhances radiopacity. It serves as an intermediate in pharmaceutical manufacturing, particularly in the production of iodinated compounds for medical imaging. Its structure allows for further chemical modifications, making it valuable in developing contrast media for angiography, urography, and other diagnostic procedures. Also investigated for use in radiolabeling applications and as a building block in specialty organic syntheses where heavy atom incorporation is required.
