Abstract

The invention provides a detection method of cyantraniliprole and metabolite J9Z38 in fish. The method includes: extraction, purification, determination, fortified recovery test to obtain the fortified recovery of cyantraniliprole and J9Z38 and relative standard deviation (RSDs); detection of the minimum detectable amounts of cyantraniliprole and J9Z38; and acquisition of the minimal detectable concentration of cyantraniliprole and J9Z38 in fish. The present invention establishes an analysis detection method of cyantraniliprole and its metabolite J9Z38 in fish. Acetonitrile is employed for extraction, n-hexane is used for removing fat, protein and other impurities in fish, and the purification separation effect is good. The method has the advantages of relatively simple pretreatment process, high recovery rate, good repeatability, good purification separation effect, and low minimal detectable concentration, and is suitable for analysis and detection of cyantraniliprole and metaboliteJ9Z38 in fish.

Description

technical field [0001] The invention relates to pesticide detection, in particular to a method for detecting cyantraniliprole and metabolite J9Z38 in fish. Background technique [0002] Cyantraniliprole (Cyantraniliprole) is another new anthranilamide insecticide developed by DuPont after chlorantraniliprole. It has the characteristics of high efficiency, low toxicity, novel mechanism of action, safety to non-target organisms, and no cross-resistance to existing insecticides. Cyantraniliprole has excellent control effect especially on piercing-sucking mouthparts pests, has broad application prospects, and has attracted widespread attention. [0003] The chemical name of cyantraniliprole is 3-bromo-1-(3-chloro-2-pyridyl)-N-{4-cyano-2-methyl-6-[(methylamino)carbonyl]phenyl }-1H-pyrazole-5-carboxamide; the chemical structure is [0004] [0005] Molecular formula C 19 h 14 BrClN 6 o 2 , molecular weight 473.7. Cyantraniliprole is a white powder with a melting point of...
