The indirect resolution of five beta-adrenoreceptor blocking agents (propranolol, oxprenolol, pindolol, metoprolol, and atenolol) using precolumn derivatization with (+)-1-(9-fluorenyl)ethyl chloroformate (FLEC), and capillary electrochromatography (CEC) is reported. Three octadecylsilanized (ODS) silica gel-based stationary phases, differing in particle diameter and carbon

A method for the determination of the R-(+) and S-(-) enantiomers of propranolol in blood was developed. After extraction with heptane-isopentanol and derivatization with (+)-1-(9-fluorenyl)ethyl chloroformate, excess reagent was removed using solid-phase extraction. The enantiomers were separated on an achiral

An indirect enantioseparation method for robust and precise determination of D-Carnitine (D-C) in L-Carnitine (L-C) in the range of 0.1-1.0% is presented. The method is based on derivatization of Carnitine with (+)-[1-(9-fluorenyl)-ethyl]-chloroformate ((+)-FLEC). The two diastereomers are subsequently separated of
