Descripción

General description

Heptafluorobutyric anhydride (HFB) is a derivatizing reagent. It provides facile and sensitive way for detecting and elucidating structure of numerous alkyl-chain homologs.

Application

Learn more in the Product Information

GC derivatizing agent used to prepare volatile derivatives of amino acids and other biologically active compounds.

HFB was used as derivatizing agent in analysing platelet-activating factor using GC-MS.

Suitable for the derivatization of aldosterone, digoxin, digitoxin and metabolites, estradiol, postaglandins F_1α and F_2α,3-oxo-Δ⁴-steroids, and testosterone.

Packaging

Derivatization reagent used in a GC-MS analysis of stereoisomer content of synthetic peptides.

Other Notes

Reagent for heptafluorobutyrate, 3-enol heptafluorobutyrate, 17-heptafluorobutyrate, heptafluorobutyrate and heptafluorobutyryl.

Selection of electrophoric derivatives of 1-aminopyrene and 2-aminofluorene for determination by gas chromatography with electron-capture negative-ion mass spectrometry.

J Bakthavachalam et al.

Journal of chromatography, 500, 373-386 (1990-02-02)

Several electrophoric derivatives of 1-aminopyrene and 2-aminofluorene were prepared. Reagents such as heptafluorobutyryl chloride, pentafluorobenzoyl chloride, pentafluorobenzyl bromide and pentafluorobenzaldehyde, alone and in certain combinations, were employed. The ease of formation, yield, stability and fragmentation by gas chromatography with electron-capture

Analysis of platelet-activating factor by GC-MS after direct derivatization with pentafluorobenzoyl chloride and heptafluorobutyric anhydride.

S T Weintraub et al.

Journal of lipid research, 31(4), 719-725 (1990-04-01)

Parallel analysis of platelet-activating factor (PAF) using chemical ionization gas chromatography-mass spectrometry after direct derivatization with pentafluorobenzoyl chloride (PFB) and heptafluorobutyric anhydride (HFB) provides a facile and highly sensitive means for detecting and elucidating the structure of the numerous alkyl-chain

Gas-chromatographic separation of stereoisomers of dipeptides.

Ralf Pätzold et al.

Chirality, 18(7), 551-557 (2006-05-10)

Synthetic dipeptides comprising mixtures of enantiomers, diastereomers, or sequential isomers were converted into their N-perfluoroacetyl dipeptide esters (perfluoroacetyl: trifluoroacetyl, pentafluoroacetyl, heptafluorobutyryl; ester: methyl, 1-propyl, 2-propyl, 2,2,2-trifluoroethyl) and analyzed by GC-MS on the chiral stationary phases Chirasil-L-Val and Lipodex-E using helium
