丁氟螨酯是一种新型杀螨剂，具有高效、低残留的特点.本文对其红外吸收光谱（IR）、紫外吸收光谱（UV）、质谱（MS）及核磁共振（NMR）波谱（包括1H NMR、13C NMR、DEPT、1H-1H COSY、1H-13C HSQC、1H-13C HMBC）进行了测定，分析了其UV和IR谱图特征吸收峰对应的基团，并对其1H和13C NMR信号进行了归属，确证了丁氟螨酯的结构.该研究将为丁氟螨酯的其他相关研究提供参考.
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.
