Abstract

Enantiomer separation of synthetic pyrethroids was carried out on different chiral HPLC columns. In particular, the study provided useful information on the direct resolution of pyrethroids with and without α-ciano groups. The study indicated that polymeric chiral stationary phases based on cellulose derivatives are the most appropriate for the stereoisomer separation of cis-Biphenthrin , Resmethrin and (1R)-Phenothrin, whereas multiple-interaction CSPs, like (S)-1-(α-naphthyl)-ethylamine/(S)-tert-leucine, are more selective for Cyfluthrin.
