"Application: Reagent for amino group protection recently used in the synthesis of a bicyclic proline analog. Reagent for derivatizing amino acids for HPLC amino acid analysis and for preparing N-Fmoc amino acids for solid-phase peptide synthesis. Amino acid derivatizing agent for HPLC analysis. N-protecting reagent for peptide and oligonucleotide syntheses. Fluorenylmethyloxycarbonyl chloride (Fmoc-Cl) is a chloroformate ester. It is used to introduce the fluorenylmethyloxycarbonyl protecting group as the Fmoc carbamate."
