NEW DERIVATIVES OF 2,4,6-TRIIODO-ISOPHTHALIC ACID,PROCESSES FOR THEIR SYNTHESIS AND X-RAY CONTRASTING MATERIALS CONTAINING THESE

摘要

Novel, radio-opaque compounds comprising water-soluble bis-[N-{3,5-bis-(hydroxyalkylaminocarbonyl)-2,4,6-triiodo-phenyl}-N-( alpha -hydroxyacyl)-amino]-alkanes are disclosed for use as X-ray contrast agents. These compounds are relatively simple to synthesize, possess low toxicity and have good stability as well as resistance to hydrolysis. Methods for preparation and use of the compounds are also disclosed.
