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.
Clear borosilicate glass, high hydrolytic resistance (Type I)
Analysis Note
Suitable for derivatization of aldosterone, digoxin, digitoxin and metabolites, estradiol, postaglandins F1α and F2α, 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]
Reagent for 3-enol heptafluorobutyrate, heptafluorobutyrate, heptafluorobutyryl, 17-heptafluorobutyryl and 17-heptafluorobutyrate.

Methods for ultra trace detection of endocrine disruptive chemicals (EDCs) are needed because of their low levels of impact. Twenty-one EDCs were selected, including 17beta-estradiol, 17alpha-ethinylestradiol, 17beta-testosterone and bisphenol A. Derivatisation with eight different fluorine containing compounds was examined. All
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

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
