説明
9-Fluorenylmethyl chloroformate (Fmoc-C1) is a significant biochemical reagent introduced by Carpino. It has been widely utilized as a reagent for the introduction of the 9-fluorenylmethoxycarbonyl (Fmoc moiety) in both peptide and nucleotide synthesis, as well as serving as a coupling agent in peptide synthesis[1]. Furthermore, Fmoc-C1 can function as a versatile fluorescent labeling reagent for primary and secondary amines[2].
使用
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).
一般的な説明
Fmoc chloride is a derivatizing agent.
製法・合成法
純化方法
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.
