Compounds of the formula: ##STR1## wherein R represents the group --CH.sub.2 CH.sub.2 OH or --CH.sub.2 CHOHCH.sub.2 OH, particularly in racemic or optically active form, are employed as active ingredients in X-ray contrast agents for intracerebral, but particularly for vascular use. The compounds are prepared by reacting 5-(N-acetamido)-2,4,6-triiodo-N,N'-bis-(2,3-dihydroxypropyl)isophthalamide or an O-acetyl derivative thereof with an appropriate hydroxyalkylating agent and subsequently, if necessary, hydrolysing any unwanted O-acetyl groups.
式(I)化合物: ##STR1## 其中R代表基团--CH₂CH₂OH或--CH₂CHOHCH₂OH,特别是在外消旋或光学活性形式中,被用作X射线造影剂的活性成分,主要用于脑血管,但特别是用于血管使用。这些化合物是通过反应5-(N-乙酰氨基)-2,4,6-三碘-N,N'-双-(2,3-二羟基丙基)异酞酰胺或其O-乙酰化衍生物与适当的羟基烷基化剂,并在必要时随后水解任何不需要的O-乙酰基团来制备的。
