General description

1-(Heptafluorobutyryl)imidazole, also known as HFBI, is an acylating derivatization reagent. It is a mild amine-group derivatizing agent. HFBI doesn’t produce acidic by-products in reaction, and the unutilized reagent doesn’t damage the chromatographic process. Post derivatization reaction, the HFB (Heptafluorobutyryl) derivatives are analyzed chromatographically.

Application

1-(Heptafluorobutyryl)imidazole is used as a derivatizing agent for analysing Sulphur mustard metabolites. It is suitable to study dispersive derivatization of degradation products.

Biochem/physiol Actions

Mild amine-group derivatizing reagent; non-acidic by-product prevents decomposition and reduces GC column degradation.
