Description and Uses

Heptafluorobutyric anhydride (HFAA) is frequently used as an acylating agent for the derivatization of primary and secondary amines (Walle and Ehrsson, 1971). Commercially available Heptafluorobutyric anhydride may afford low yields of the derivative due to the presence of Heptafluorobutyric acid (Moodie et al., 1985). This contaminant may be removed by ditillation over phosphorus pentoxide (Walle and Ehrsson, 1970).
HFAA is used to increase volatility of an analyte, and to introduce fluorine atoms for better detection limits in gas chromatography applications.
