Descrizione generale

1-(Trifluoroacetyl)imidazole (N-(Trifluroroacetyl)imidazole) is an effective reagent for specific trifluoroacetylation of an aminomethyl side chain of certain nucleosides.

Applicazioni

1-(Trifluoroacetyl)imidazole may be employed as derivatization reagent for the detection of mustard gas degradation products, thiodiglycol and thiodiglycol sulfoxide using gas chromatography-tandem mass spectrometry. It may be used as reagent for the trifluoroacetylation of amines. It was used for derivatization of ethanolamine phospholipid-alkenal Michael adducts for GC-MS analysis. It was used in the determination of quinolinic acid, a kynurenine metabolite, by GC/MS.

Hydroxy-alkenals, such as 4-hydroxy-2(E)-nonenal (4-HNE; from n-6 fatty acids), are degradation products of fatty acid hydroperoxides, including those generated by free radical attack of membrane polyunsaturated fatty acyl moieties. The cytotoxic effects of hydroxy-alkenals are well known and are mainly
