9-Fluorenylmethyl chloroformate Chemical Properties,Uses,Production

Chemical Properties

White to off white crystalline powder

Uses

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).

Uses

9-Fluorenylmethyl chloroformate can be used as N-protecting reagent for oligonucleotide and peptide syntheses.

Uses

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.

Safety Profile

A poison. Mutation data reported. A corrosive. When heated to decomposition it emits toxic vapors of Cl-.

Purification Methods

If the IR contains no OH bands (at ~3000 cm-1) due to the hydrolysis product 9-fluorenylmethanol, then purify it by recrystallisation from dry Et2O. IR (CHCl3) has a band at 1770 cm-1 (C=O), and the NMR (CDCl3) has  at 4-4.6 (m 2H, CHCH2) and 7.1-7.8 (m, 8 aromatic H) ppm. The azide (FMOC-N3) has m 89-90o (from -1hexane) and IR (CHCl3) at 2135 (N3) and 1730 (C=O) cm , and the carbazate (FMOC-NHNH2) has m 171o(dec) (from nitromethane), IR (KBr) 3310, 3202 (NH) and 1686 (CONH) cm-1.
