摘要: Dicarboxylic acid bis(3,5-dicarbamoyl-2,4,6-triiodoanilides) of the formula ##STR1## wherein R 1 is lower straight-chain or branched-chain mono- polyhydroxyalkyl; 2 hydrogen, alkyl ; 3 hydrogen alkyl; and X a direct bond alkylene interrupted by one more oxygen substituted hydroxy alkyl, are useful in x-ray contrast media.
