General description

(+)-1-(9-Fluorenyl)ethyl chloroformate is a highly fluorescent compound1 commonly used as a chiral derivatizing agent for the separation of racemates prior to reversed-phase HPLC analysis.

Application

  • Chiral analysis of β-methylamino alanine (BMAA) enantiomers: Details the use of (+)-1-(9-fluorenyl)-ethyl chloroformate (FLEC) for derivatization followed by LC-MS/MS analysis, improving the understanding of amino acids′ stereochemistry (Zurita et al., 2019).
  • Enantioselective micellar electrokinetic chromatography of dl‐amino acids: Utilizes (+)-1-(9-fluorenyl)ethyl chloroformate derivatization combined with UV-induced fluorescence detection to analyze amino acids, enhancing analytical methodologies (Prior et al., 2018).
