A process for preparing iopamidol by using a c<sb>1</sb>-c<sb>5</sb> monoalkylether of a c<sb>2</sb>-c<sb>10</sb> alkylene-glycol

摘要

A process for purifying iopamidol consisting of crystallizing this product from a C1-C5 monoalkylether of a C2-C10 alkylen-glycol. This process allows to obtain crystalline iopamidol in a high yield with optimum physical-chemical properties.
