用途

用途

ペプチド合成は、医薬品工業、食品化学工業、基礎生化学などの分野で、ペプチドの構造確認、機能解明、物性研究のための材料提供や、貴重なペプチドの大量合成および天然物より優れた類似体の創作を目的に幅広く行われています。

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.
