1,3-BIS-[3-(MONO- OR POLY-HYDROXY)ACYLAMINO-5-(MONO- OR POLY-HYDROXYALKYL)AMINOCARBONYL-2,4,6-TRIIODO-BENZOYL-AMINO]-HYDROXY- OR HYDROXYALKYL-PROPANES, THEIR METHODS OF PREPARATION AND X-RAY CONTRAST MEDIA 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.
