General description
(+)-1-(9-Fluorenyl)ethyl chloroformate [(+)-FLEC] is a chiral derivatizing reagent. It helps in separating enantiomers of α-amino acids, as well as helps in determining its optical purity using HPLC method.
Application
(+)-FLEC may be used in enantioselective analysis of glufosinate using reversed-phase high-performance liquid chromatography system coupled with a fluorescence detection system.
Physical form
solution, 5 mg in 1 mL acetone
Other Notes
Chiral derivatizing agent for primary and secondary amino acids and amines. The derivatives are separated by reversed-phase LC with fluorescence detection for determining the enantiomeric purity

In the liquid chromatographic analysis of pharmaceuticals, two challenges are often encountered: detectivity and chiral separations. Propranolol, a beta adrenergic blocker, is a pharmaceutical compound that faces both of these limitations. In this study, both limitations are overcome simultaneously using
