General description

Heptafluorobutyric anhydride is a perfluoroacylated acylation reagent, that forms stable, volatile derivatives with alcohols, amines, and phenols. It is majorly used to prepare electron-capturing derivatives for GC/electron capture detection. It is generally used with an acid scavenger, to help drive the reaction to completion and to prevent column damage from acidic by-products of the derivatization reaction. It is also used for the frequent testing of drugs of abuse such as, amphetamines and phencyclidine by GC-MS technique.

Application

Packaging

Clear borosilicate glass, high hydrolytic resistance (Type I)

Analysis Note

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

Other Notes

HFAA acylates amines, amino acids and other compounds. HFBA derivatives are highly volatile: used in GC separation[1][2]

Handbook of Analytical Derivatization Reactions, 454-454 (1979)

GC/MS identification and quantification of constituents of bacterial lipids and glycoconjugates obtained after methanolysis as heptafluorobutyrate derivatives.

Anne Bohin et al.

Analytical biochemistry, 340(2), 231-244 (2005-04-21)

In previous articles [Anal. Biochem. 284 (2000) 201; J. Lipid Res. 43 (2002) 794], we reported that the GC/MS identification and quantification of nearly all constituents of glycolipids could be obtained on the same sample in a single GC/MS analysis

Validation of a headspace solid-phase microextraction-GC-MS/MS for the determination of ethyl glucuronide in hair according to forensic guidelines.

Ronald Agius et al.

Forensic science international, 196(1-3), 3-9 (2010-01-12)

The analysis of ethyl glucuronide (EtG) in hair is a powerful tool for chronic alcohol abuse control because of the typical wide detection window of the hair matrix and due to the possibility of segmentation, allowing evaluation of alcohol consumption

Presence of phenylethylamine in hallucinogenic Psilocybe mushroom: possible role in adverse reactions.

O Beck et al.

Journal of analytical toxicology, 22(1), 45-49 (1998-03-10)

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

Determination of low levels of poly(ethylene glycol) 400 in plasma and urine by capillary gas chromatography-selected ion-monitoring mass spectrometry after solid-phase extraction.

C Fakt et al.

Journal of chromatography. B, Biomedical sciences and applications, 700(1-2), 93-100 (1997-12-09)

A convenient and sensitive method for the quantitative determination of poly(ethylene glycol) 400 in plasma and urine with capillary gas chromatography-mass spectrometry has been developed. The sample preparation involves solid-phase extraction with subsequent derivatization with heptafluorobutyric anhydride, which proved to
