摘要: A method for refining sugammadex sodium is provided: adding a protective agent to crude sodium, and obtaining pure by performing recrystallization under the protection of inert gas. Among them, one or mixture two more, in any ratio, selected from group consisting mercaptoethanol, thioglycolate, thioglycolate ester, mercaptopropionate, mercaptopropionate glutathione, cysteine, cystamine, dithioerythritol, dithiothreitol, trisubstituted organophosphorus compound, salt compound. The simple operation, high product purity, good economy, more suitable industrial production.
