Abstract

The enantiomeric separation of pyriproxyfen(Sumilarv^®), a new insect growth regulator- was investigated on several commercially available chiral stationary phases consisting of cellulose esters coated on silica. The resolution has been only achieved by using a cellulose Iris (4-methylbenzoate)-coated silica gel. The enantiomeric elution order changed according to the steric bulk of the alcohols. The possible mechanisms of the reversal of elution order are discussed.
