This invention relates to compounds of the formula: ##STR1## in which: R.sub.1 represents a hydrogen atom or a radical of the formula ##STR2## in which R.sub.4 and R.sub.5 represent, independently of each other, a hydrogen atom or a lower alkyl radical, R.sub.2 represents a hydrogen atom or a lower alkanoyl radical, R.sub.3 represents a hydrogen atom, a lower alkyl radical or a lower alkanoyl radical, n is 3 or 4, And their lower alkyl esters and their salts with pharmaceutically acceptable bases. Said compounds are useful as X-ray contrast media.
本发明涉及公式为:##STR1##的化合物,其中:R.sub.1代表氢原子或公式##STR2##中的基团,其中R.sub.4和R.sub.5分别独立地表示氢原子或较低的烷基基团,R.sub.2表示氢原子或较低的脂肪酰基基团,R.sub.3表示氢原子、较低的烷基基团或较低的脂肪酰基基团,n为3或4,以及它们的较低烷基酯和与药用可接受碱的盐。所述化合物可用作X射线造影剂。
