Process for the crystallization from a linear or branched (C5-C6) alcohol or their mixtures of (S)-N,N'-bis[2-hydroxy-1-(hydroxymethyl)ethyl]-5-[(2-hydroxy-1-oxopropyyl)amino]-2,4,6-triiodo-1,3-benzendicarboxamide

摘要

Disclosed is a new process for the crystallization of (S)-N,N'-bis[2-hydroxy-1-(hydroxymethyl)ethyl]-5-[(2-hydroxy-1-oxopropyl)amino]-2,4,6-triiodo-1,3-benzendicarboxamide (I), using a linear or branched (C5-C6) alcohol or their mixtures.
