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