Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)

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.
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.
