詳細

アプリケーション

1,4-Difluorobenzene has been used as a dopant, in order to ionize the soluble organic species present in huolinguole lignite coal by using atmospheric pressure photoionization technique coupled with mass spectrometry (APPI-MS). It also plays role of an internal standard in investigating the ¹⁹F nuclear magnetic resonance (NMR) spectrum of electrophilic trifluoromethyl thiolating agents prepared from nucleophilic tetramethylammonium trifluoromethyl thiolate.
