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.

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 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
