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.[1]
Application
(+)-FLEC may be used in enantioselective analysis of glufosinate using reversed-phase high-performance liquid chromatography system coupled with a fluorescence detection system.[2]
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[3]

After the derivatization of D- and L-amino acids with (+)-1-(9-fluorenyl)ethyl chloroformate, nineteen amino acids were separated into their D- and L-enantiomers and from other physiological amino compounds by reversed-phase ion-pair high-performance liquid chromatography. The separation was performed by three separate

A method to measure total hydroxyproline in human urine was developed. Primary amino acids were derivatized with ortho-phthaldialdehyde, followed by derivatization of imino acids with 9-fluorenylmethyl chloroformate. The fluorescent 9-fluorenylmethyl chloroformate derivatives were separated by reversed phase high-performance liquid chromatography.

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

A sensitive and selective high-performance liquid chromatographic method for the determination of reboxetine enantiomers in human plasma was developed. Although two chiral centres are present in reboxetine, its stereospecific synthesis leads to two rather than four possible enantiomers. After extraction
