Opis ogólny

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.

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
