Abstract High performance liquid chromatography (HPLC) and electrospray ionization mass spectrometry (ESI‐MS) have been utilized to analyze the synthesized 2‐(2‐arylaminomethylphenoxy)pyrimidine derivatives, which are a new kind of environmentally benign herbicides and have passed the temporary pesticide registration. The identification of main product and impurities has been achieved according to the UV and mass spectra. Moreover, one impurity, introduced by the raw material in the last step of the synthetic route, was identified by GC‐MS analysis. It can be concluded that the combination of chromatography and mass spectrometry, including LC‐MS and GC‐MS, provided a vital tool of the pesticide science.
