摘要

2-Amino-1-(1,3-dioxolan-4-yl)ethanol compounds of formula (I) (I) wherein R1 and R2 are identical or different and can be hydrogen or a lower alkyl group of 1-4 carbon atoms; or when R2 is an alkyl group of 1-4 carbon atoms, R1 can also be an alkoxy group of 1-4 carbon atoms; or R1 and R2 combined form an alkylene residue of 5 or 6 carbon atoms, are especially suited as intermediates in the production of opacifying compounds useful in X-ray contrast media.
