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 F1α and F2α, 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.

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 use of mushrooms containing the hallucinogenic substance psilocybin for intentional intoxication is relatively common. Occasionally, this results in adverse reactions with typical tachycardia that is not evidently caused by psilocybin. This study demonstrates the presence of phenylethylamine in the
