Novel x-ray contrast agents, compositions and methods

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-hdyroxyethyl)glycolamido]-N'-methyl-2, 4,6-triiodoisophthalamide are provided.
