The Uses of N-Heptafluorobutyrylimidazole
1-(Heptafluorobutyryl)imidazole is used in gas chromatography for the determination of various pharmaceutical compounds like retronecine in biological matrixes. It acts as a reagent for derivatize amine-groups. It plays an essential role to reduce GC column degradation due to its non-acidic property. It is an acylating agent, which converts thermally unstable compounds to its more volatile derivative and then made suitable for GC analysis.
General Description
May form a precipitate and may darken on storage-will not effect performance.
Biochem/physiol Actions
Mild amine-group derivatizing reagent; non-acidic by-product prevents decomposition and reduces GC column degradation.
