Application

2,3,5,6-Tetrafluoro-4-(trifluoromethyl)benzyl bromide (4-(trifluoromethyl)-2,3,5,6-tetrafluorobenzyl bromide, TTBB) may be employed as an alternate of pentafluorobenzyl bromide (PFBB) in electrophoric derivatization reactions prior to detection during gas chromatography-electron-capture negative ion mass spectrometry (GC-ECNI-MS). TTBB may be employed as derivatization reagent for the characterization and quantitation of DNA and hemoglobin adducts.
