The invention relates to novel poly-iodinated compounds of general formula: ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10, identical or different, are selected from an iodine atom, a group of formula ##STR2## provided that at least two of the R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 groups represent an iodine atom, utilizable in contrast media for radiography. The invention also relates to a process for the preparation of these compounds as well as a contrast medium containing them.
该发明涉及一种新型多碘化合物,其一般式为:##STR1##其中R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5、R.sub.6、R.sub.7、R.sub.8、R.sub.9和R.sub.10,相同或不同,选自碘原子、##STR2##式的基团,但至少有两个R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5、R.sub.6、R.sub.7、R.sub.8、R.sub.9和R.sub.10基团代表碘原子,可用于放射造影对比介质。该发明还涉及一种制备这些化合物的方法以及含有它们的对比介质。
