High Resolution Mass Spectrometry Fragmentation Rules of Etomidate and Its Structural Analogues by FAN Xian-yu, ZHU Xue-yan, WANG Xin, XIANG Ping, ZHAO Jun-bo

“…ObjectiveTo explore the characteristic fragment ions, ion abundance ratios and mass spectrometry fragmentation rules of etomidate and its structural analogues by using gas chromatography-quadrupole/orbitrap mass spectrometry （GC-Q/Orbitrap MS） and liquid chromatography-linear ion trap quadrupole-orbitrap mass spectrometry （LC-LTQ-Orbitrap MS） techniques, providing important data support for the identification and prediction of etomidate structural analogues.MethodsGC-Q/Orbitrap MS and LC-LTQ-Orbitrap MS were used to analyze metomidate, etomidate, isopropoxate and propoxate, to obtain their GC high resolution mass spectra and LC high resolution mass spectra.ResultsUnder the electron impact （EI） ion source mode, etomidate, metomidate and the other two analogues all produced their molecular ions and seven identical fragment ions （m/z 77.038 6, 79.054 2, 95.024 0, 105.069 9, 143.073 0, 172.099 5 and 199.086 6）, among which isopropoxate and propoxate also produced characteristic fragment ions m/z 216.089 3. …”
