说明

1,4-二氟苯已被用作掺杂剂,以通过使用常压光电离技术与质谱联用 (APPI-MS) 电离存在于霍林郭勒褐煤中的可溶性有机物。 它还在研究由亲核四甲基铵三氟甲基硫醇盐制备的亲电子三氟甲基硫醇化剂的 19F 核磁共振 (NMR) 光谱中发挥内标作用。

应用

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