Abstract
Non-ionic polyiodo saccharidic ether substituted anilines are provided as contrast media, the ether being non-glycosidyl. The compounds have excellent physical properties in having acceptable water solubility or capable of stable suspension, relatively low osmotic pressure, good thermal stability, so as to be heat sterilizable, and a high iodine proportion. The compounds can be prepared from polynitroaromatics by substitution and reduction.
