Pharmakologische Informationen
MeSH Pharmacological Classification
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)
Verwendung und Herstellung
Uses
Perfluorocarboxylic acids include Perfluoroacetic, Perfluoropropionic, Perfluorobutyric, Perfluorovaleric, Perfluorocaproic, Perfluoroheptanoic, Perfluorocaprylic, Perfluorononanoic, Perfluorocapric, Perfluoroundecanoic, and Perfluorododecanoic acid; These long-chain perfluoroalkanecarboxylic acids and their salts are used as wetting, dispersing, emulsifying, and foaming agents. They greatly reduce surface tension in aqueous solutions. [Ullmann]

Anwendungen
VerwendenHeptafluorobutyric acid (HBFA) has been used widely for purifying neuropeptides because of its excellent resolution. The use of heptafluorobutyric acid as a volatile ion-pair reagent in the high-performance liquid chromatographic isolation of SB-223070 John K. Heptafluorobutyric acid is a strong acid and ion-pairing agent that is used in analytical chemistry, notably in HPLC and in gas chromatography/mass spectrometry (GC/MS), in a similar manner to trifluoroacetic acid (TFA). The strong acidity of HFBA ensures that other acidic groups such as carboxylic acid moieties on biomolecules remain protonated, and thus the biomolecule samples are able to interact with organic solvents in such processes as reverse phase chromatography. The longer alkyl chain of HFBA makes it more hydrophobic than TFA, and thus HFBA can be utilized with more hydrophobic samples. HFBA (0.1%) has been used in the mobile phase of an HPLC/LC-MS protocol for the detection of marine bacterioplankton sideophores.A study of the effects of various acids, including HFBA, on the resolution of intact proteins by reversed-phase LC/ESI-MS has been published.A modified version of the peptide ladder sequencing technique that incorporates allyl isothiocyanate and HFBA has been reported.
