Drug Information

Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)

Heptafluorobutyric anhydride Use and Manufacturing

Uses

As a GC derivatizing agent, Heptafluorobutyric anhydride is used to prepare volatile derivatives of amino acids and other biologically active compounds. 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.
