The diastereomers of cypermethrin and permethrin have been resolved on an irregular silica column. Complete separation of three of the four enantiomeric pairs of cypermethrin was achieved with reasonable retention times (<50 min) by direct injection of the separated diastereomers onto a cellulose...
