Description

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

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