Fenoxaprop-P-ethyl  Determination of enantiomeric purity
Content Handbook M
Outline of method
Fenoxaprop-P-ethyl and fenoxaprop-M-ethyl are determined by normal phase HPLC on an enantioselective stationary phase (silica bonded permethylated beta-cyclodextrin) using UV-detection at 237 nm. The fenoxaprop-P-ethyl percentage in the racemate is calculated.
The method is usable for TC, EW, EC, SE and OD-formulations.
