N-Heptafluorobutyrylimidazole Usage And Synthesis
| 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. |
