Allgemeine Beschreibung

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.

Anwendung

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. Wirkung

Mildes Amin-Gruppen Derivatisierungsreagens; nicht-saures Nebenprodukt verhindert Zersetzung und reduziert den GC-Säulen Abbau.
