Gas-Liquid Chromatographic Determination of m-Phenoxybenzyl cis, trans-(±)-3-(2,2-Dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate in Aqueous Formulations
Keyword(s):
Abstract A simple and rapid gas-liquid chromatographic (GLC) method was developed for the analysis of aqueous solutions of FMC 33297 (m-phenoxybenzyl cis,trans-(±)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate). The compound is extracted from aqueous solution with benzene and cleaned up by liquid chromatography. The sample extracts are analyzed by GLC with a flame ionization detector and quantitated by comparing integrator counts of extracts with those of standards. Recoveries of FMC 33297 were 90—100%. The method has good precision (the standard deviation for 4 determinations of a 0.002394% formulation was 6 × 10−6) and is sensitive to 0.00004% active ingredient by weight.
