Hazard Information	Back Directory
[Chemical Properties] N-Heptafluorobutyrylimidazole is colorless liquid
[Uses] 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.
[Uses] N-Heptafluorobutyrylimidazole is a derivatization agent used in gas chromatography for determination of various pharmaceutical compounds such as retronecine in biological matrixes.
[General Description] May form a precipitate and may darken on storage-will not effect performance.
[reaction suitability] reagent type: derivatization reagent reaction type: Acylations
[Biochem/physiol Actions] Mild amine-group derivatizing reagent; non-acidic by-product prevents decomposition and reduces GC column degradation.
