Iodinated aromatics are organic compounds that contain iodine atoms attached to an aromatic ring, which is a stable structure made up of carbon atoms arranged in a cyclic pattern. These compounds are significant in various fields, including pharmaceuticals and imaging, due to their unique chemical properties and ability to enhance contrast in medical imaging techniques like X-rays and CT scans. The presence of iodine in these compounds often increases their biological activity and can improve the effectiveness of certain drugs. Iodinated aromatics are also used in the synthesis of other chemical compounds, making them valuable in both industrial and research applications.
