    呋喃磺草酮原药中主要杂质的结构鉴定及其合成

    Structural identification and synthesis of main impurities in tefuryltrione

    • 摘要: 针对HPPD除草剂呋喃磺草酮原药生产中产生的3个质量分数均大于0.1%的主要杂质,通过高效液相色谱、核磁共振氢谱和高分辨质谱对3个杂质的结构进行了结构鉴定,发现其中2个为未见文献报道的化合物。结合生产工艺对杂质产生的路径进行了分析,并成功进行了合成。该研究对呋喃草酮原药质量控制和安全产生具有重要意义。

       

      Abstract: In the preparation of tefuryltrione, three main impurities over 0.1%(wt) were detected by high-performance liquid chromatography. The structures of impurities were characterized by 1H NMR and HRMS. Two of those compounds were novel compounds. Then the impurities were synthesisezed by the modified synthetic route of tefuryltrione. The work will contribute to the quality control and safety production of tefuryltrione.
