    摘要: The compound N-(2,3-dihydroxypropyl)-5-[N-(2-hydroxyethyl)-glycolamido]-N'-methyl-2,4,6-triiodoisophthalamide and similar such compounds may be used as x-ray contrast agents which are water-soluble, safe and in an aqueous solution are non-viscous. Methods of preparing N-(2,3-dihydroxypropyl)-5-[N-(2-hydroxyethyl)-glycolamido]-N'-methyl-2,4,6-triiodoisophthalamide and the analogous compounds are provided.
