Liquid chromatographic method for determination of cyfluthrin in technical and formulated products

, : Liquid chromatographic method for determination of cyfluthrin in technical and formulated products. Journal of the Association of Official Analytical Chemists 73(4): 595-598

A liquid chromatographic method for determination of cyfluthrin (Baythroid, Tempo) diastereomers in technical and formulated products has been developed. Samples are dissolved in dioxane-hexane and analyzed by normal-phase liquid chromatography using acetophenone as an internal standard. The method is applicable to technical Baythroid, Baythroid 2 EC, Tempo 20 WP, and granular formulations. The method separates all 4 diastereomers of cyfluthrin and all impurities in less than 19 min.
