Cyflumetofen is a new type of acaricide with high efficiency and low residue. In this work, the compound was characterized by infrared absorption (IR), ultraviolet absorption (UV) and mass spectrometry, as well as nuclear magnetic resonance spectroscopy (1H NMR, 13C NMR, DEPT, 1H-1H COSY, 1H-13C HSQC and 1H-13C HMBC). The characteristic absorption peaks in the UV and IR spectra were discussed. The 1H and 13C NMR signals of cyflumetofen were assigned, and the two-dimensional signals were used to elucidate its structure. |
