✦ Synopsis

The two enantiomers of fenpropanate and the four enantiomers of fenvalerate were separated on a commercially available NH,-bonded column containing (R)-N-(3&dinitrobenzoyl)phenylglycine as chiral phase. This column also separated three of the four possible enantiomer pairs of cypermethrin isomers and two of the four pairs of BAY FCR 1272 isomers. Conditions for these separations and an application to the analysis of cypermethrin residues in soil are described. The chromatographic behavior of the diastereomers of these materials and other pyrethroid insecticides on silica and NH,-bonded columns was also examined.
