A study on the separation of synthetic pyrethroid stereoisomers by HPLC.
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 alpha-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-(alpha-naphthyl)-ethylamine/(S)-tert-leucine, are more selective for Cyfluthrin.
