1,2-BIS-/3-(MONO- OR POLYHYDROXY)-ACYL-AMINO-5-(MONO- OR PLYHYDROXY-ALKYL)-QMINO-CARBONYL-2,4,6-TRIIODO-BENZOYL-AMINO/-HYDROXY-PROPANES OR HYDROXY-ALKYL ONES, METHOD FOR PRODUCING SAID COMPOUNDS AND RADIOGRAPHIC CONTRAST MATERIALS CONTAINING THEM

摘要

Symmetrical or asymmetrical 1,3-bis-[3-(mono- or poly-hydroxy)acylamino-5-(mono- or polyhydroxyalkyl)-aminocarbonyl-2,4,6-triiodo-benzoyl-amino]-hydroxy- or hydroxyalkyl-propanes, useful to constitute the opacifying component of X-ray contrast media, are described.
