HFBI (GC Diagnostic Reagent acylation) GC108   Heptafluorobutrylimidazole, 99+% [ 32477-35-3 ]   f.w.: 264.1 daltons

HFBI is an Acylation Reagent for GC Derivatization that readily forms derivatives with phenols, alcohols, and amines suitable for ECD. The reactions are fast and mild and imidazole is not acidic, so no decomposition or corrosion occurs on columns. Perfluoroacyl imidazoles offer very effective acylation of hydroxl groups and primary and secondary amine groups.
