Abstract
Abstract Triiodized N-methyldicarboxylic acid anilides of the Formula ##STR1## wherein R 1 is hydrogen, halogen, carboxyl, N-monoacylamino, N-monoalkoxyacylamino, N-alkyl-N-acylamino, N-alkyl-N-alkoxyacylamino, N,N-diacylamino, N-acylaminomethyl, ##STR2## wherein A is alkylene of 2 or 3 carbon atoms which can be interrupted by an oxygen atom, and R 3 and R 4 are each hydrogen, lower alkyl or hydroxyalkyl, or R 3 and R 4 together with the nitrogen atom form a 5 to 7 member heterocyclic ring which can contain a further oxygen, nitrogen, or sulfur hetero atom; R 2 is halogen, hydroxy, lower alkoxy, hydroxyalkoxy or alkoxyalkoxy; and X is straight or branched alkylene of 2-14 carbon atoms interrupted by one or more oxygen or sulfur atoms, and the salts of these compounds with physiologically compatible bases are valuable radiopaque agents.
