Used as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of contrast agents for medical imaging. Its iodine content makes it valuable in creating radiopaque compounds used in X-ray and computed tomography (CT) scans. The cyclic acetal structure provides stability during synthetic transformations, allowing selective reactions at other functional sites. It is also employed in organic synthesis to introduce iodopentyl side chains into complex molecules, facilitating further derivatization in drug discovery and development.
