Spectral Analyses and Structural Elucidation of Cyflumetofen

doi:10.11938/cjmr20192723

Abstract

Abstract: 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.

Key words: nuclear magnetic resonance (NMR), structural elucidation, cyflumetofen, mass spectrometry (MS), ultraviolet absorption spectrum (UV), infrared absorption spectrum (IR)
