PROCESS FOR THE PRODUCTION OF IODINATED ORGANIC X-RAY CONTRAST AGENTS

摘要

The present invention provides a process for the production of an organic iodinated X-ray contract agent, characterized in that process control comprises vibrational (e.g., infrared, Raman or preferably near-infrared) spectroscopic monitoring of the reaction mixture in at least one of the process steps, preferably one of the final reaction steps.
