Beschreibung

Allgemeine Beschreibung

Pentafluorobenzyl bromide (PFB-Br) is a derivatization reagent. Excess reagent may be removed by reaction with an aminophenol. It is an alkylation reagent suitable for electron capture detector (ECD) detection. It is also a lachrymator.

Anwendung

It is used for the analysis of D2/E2-isoprostanes using negative ion chemical ionization-gas chromatography/mass spectrometry (NICI-GC/MS). Fatty acids may be converted to pentafluorobenzyl esters using PFG-Br and diisopropylethylamine during determination of fatty acids using NICI-GC/MS.

Sonstige Hinweise
