More Information
Summary:The present invention relates to an improved method for preparing a high-purity polyethylene glycol dialdehyde derivative. The preparation method uses, as an intermediate, a PEG-diacetal prepared by reacting polyethylene glycol methanesulfonate and a dialkoxy-1-propanol, thereby having an advantage of enabling the provision of a polyethylene glycol dialdehyde derivative having high purity and end-activity so as to be suitable as a material for medicines.
