  1. 9-Fluorenylmethyl chloroformate is an N-Protecting agent for peptides research and was used for the pre-column derivatization of the biogenic amines (BAs) cadaverine (Cad), histamine (Him), octopami ne (Ocp), phenylethylamine (Pea), putrescine (Put), spermidine (Spd), spermine (Spm), tyramine (Tym).
  2. 9-Fluorenylmethyl chloroformate can be used as N-protecting reagent for oligonucleotide and peptide syntheses.
  3. 9-Fluorenylmethyl chloroformate can act as reagent for the introduction of Fmoc-amino-protecting group, which is stable towards acids but is readily cleaved under mildly basic non-hydrolytic conditions.
