摘要
本文采用高效液相色谱-质谱-质谱联用法对烯草酮样品进行分离分析。得到烯草酮及其6种杂质的一级、二级质谱图,并总结烯草酮各杂质的结构,计算准确分子量。有助于烯草酮杂质的分析,有利于控制烯草酮原药中的杂质。
In this article, A HPLC-MS-MS method, taking program temperature was developed to separate and analyze clethodim and 6 impurities in clethodim technical material. The structure of clethodim and 6 impurities were identified and their molecular were confirmed and discussed, The content of clethodim and 6 impurities were also measured. The results showed a good repeatability and productivity.
