Web13 jun. 2005 · Iophendylate. Iophendylate is a mixture of isomers used as contrast medium, mainly for brain and spinal cord visualization. Iophendylate is a myelographic oil-ester (U.S. Patent 2,348,231). Iophendylate, which was never shown to be safe, was initially introduced for use in small amounts (1-2cc) for locating spinal tumors. WebPotassium iodide (KI) is a chemical compound that can be used as an iodide ion source for nucleophilic displacement reactions. During the electrochemical oxidation of aldehydes, it acts as a mediator. In the presence of an acid, it can cleave some ethers. KI can iodinate aromatic and organothallium compounds in the presence of an oxidizing agent.
