Application

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.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
