Heilporn, Sylvie; Kaisin, Michel; Flammang, Robert published the artcile< Study of the mass spectral fragmentation processes in dinitroquinoxalines using tandem methodologies>, Product Details of C8H4ClN3O2, the main research area is dinitro quinoxaline mass spectra fragmentation mechanism.
The fragmentations of 11 isomeric dinitroquinoxalines following electron ionization were studied, making use of tandem mass-spectrometry methodologies such as collisional activation (CA), various linked-scanning (LS) experiments, and mass-analyzed ion-kinetic-energy (MIKE) spectrometry. For 5,6- (I) and 6,7-dinitroquinoxaline (II), the most abundant fragment ion at m/z 116 is generated for II by successive losses of NO2·, CO, and NO·, whereas for I it is the result of 2 main competing fragmentation routes. 5,7-Dinitroquinoxaline fragmentation differs significantly, as an abundant and quite characteristic ion at m/z 127 results from consecutive eliminations of NO2· and HNO2. Addnl. substitution of the pyrazine or the benzene ring strongly modifies the reactivity.
European Mass Spectrometry published new progress about Fragmentation reaction. 6272-25-9 belongs to class quinoxaline, and the molecular formula is C8H4ClN3O2, Product Details of C8H4ClN3O2.
