Singh, Dilip Kumar published the artcileSynthesis and characterization of a series of N,N’-substituted urea derivatives by using electrospray ionization tandem mass spectrometry: differentiation of positional isomers, COA of Formula: C8H11NO, the main research area is urea preparation electrospray ionization mass spectrometry positional isomer differentiation.
The present study demonstrates that ESI-HR-MS/MS can be used to differentiate pairs of N,N’-substituted urea positional isomers and characterize a series of derivatives It was observed that a characteristic fragment ion was formed by the C-N bond cleavage with the elimination of an isocyanate moiety. The proposed mechanism of fragmentation was supported by the change in the fragmentation pathway upon alkylation of the NH. In order to generalize this fragmentation pattern, a series of N-alkylated ureas was synthesized and studied by mass-spectrometry.
Rapid Communications in Mass Spectrometry published new progress about Electrospray ionization mass spectrometry. 5961-59-1 belongs to class isoquinoline, name is 4-Methoxy-N-methylaniline, and the molecular formula is C8H11NO, COA of Formula: C8H11NO.
