| Abstract: | The standard reference material of quinclorac was prepared using the quinclorac of industrial product grade as the starting material. After being purified with active carbon, the quinclorac sample was further purified using silica gel column chromatograph. The standard reference material prepared was then characterized by melting point method, high performance liquid chromatography, ultraviolet spectrometry, element analysis, infrared spectroscopy, mass spectrometry, 1H nuclear magnetic resonance (NMR) and 13C NMR. The purity of the standard material prepared is determined to be over 99% by HPLC.= |
