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

A sensitive high-performance liquid chromatographic method for the determination of the enantiomers of atenolol in rat plasma has been developed. Racemic atenolol and practolol (internal standard) were extracted from alkalinized plasma (pH 12) into dichloromethane containing 3% (v/v) heptafluoro-1-butanol, and

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
