1,1,1,3,3,3-Hexafluoro-2-propanol is a solution-phase peptide chemistry solvent. [1] . This fluorinated polar solvent of high ionizing power facilitates Friedel–Crafts-type reactions, using covalent reagents in the absence of a Lewis acid catalyst. [2] .

2017年11月8日 · 1,1,1,3,3,3-Hexafluoroisopropanol (HFIP) has recently become a very popular solvent or additive with applications across the spectrum of chemistry. Analysis shows that it...

2025年1月27日 · Hexafluoroisopropanol (HFIP) is a viscous and colorless liquid with scary odorless. It is an ideal solvent for dissolving polyamides and esters, and it can be used to analyze nylon. Typically, a small amount of sodium trifluoroacetate can be added to the eluent to reduce the aggregation of the sample.

2005年12月10日 · The observed 13 C solution NMR and CD spectra of these polypeptides in HFIP and HFA revealed a distinctive influence on their conformational characteristics. The 13 C NMR spectra, as analyzed from the unique chemical shifts of C α and C β resonances of constituent residues revealed that fibroin largely assumes helical conformation(s) in both ...

The 1H-NMR titrations were performed at 25 oC in D 2 O. A solution of the CD molecule (0.6 mL, 1.0 mM) was titrated in a NMR tube with increasing amounts of HFIP stock solution (0.5 mL, 150 mM) as follows (in L): 0, 2.0, 4.0, 8.0, 40, 60, 80. The …

The results of Lioudyno et al. indicate that the fluorinated HFIP and TFA compounds have a strong ability to bind Aβ peptides and NMR could still detect the remaining concentrations in the Aβ 1...

In the 1 H NMR spectrum, the presence of signals for the methinic and two diastereotopic methylenic protons, in addition to those of the aromatic rings, confirms the formation of the expected ...

1,1,1,3,3,3-ヘキサフルオロ-2-プロパノール (HFIPまたはHFP) は，強い水素結合力，低求核性かつ強力なイオン化能などユニークな性質を併せ持っています。 このHFIPを溶媒として用いると，通常では特別な試薬や金属触媒を要する反応を温和な条件で行うことができます。 また，HFIPは酸性度を持つため，イオン対HPLCの緩衝液としても用いられています。 L. Eberson, M. P. Hartshorn, O. Persson, F. Radner, Chem. Commun. 1996, 2105. A. Apffel, J. A. Chakel, …
