    摘要: The present invention provides a novel method for preparing highly pure calcobutrol using an intermediate (butrol) of gadobutrol without using highly pure gadobutrol. The present invention is capable of obtaining highly pure calcobutrol with high yield through a simple and environment-friendly process, and thus can easily be mass produced.

    摘要: The present disclosure relates to a novel method for preparing high-purity gadobutrol. The present disclosure can be easily applied to a large scale production because purity of intermediate can be managed via simple and mild process and accordingly, high-purity or ultra high-purity gadobutrol that has higher purity than previous gadobutrol can be prepared in high yield therethrough.
