Investigation on the Mechamism of Mass Spectrometeric Fragmentation of Ketorolac and Its Esters and Amidts

In the present investigation on the mass spectrometric fragmentation of ketorolac and its esters and amidts,it was found that the process of fragmentation involves two diffrent hydrogen-rearrangment reactions. The mass spectrometric fragementation pro-cess of new compounds was studied in detail,obtaining the evidence of high-resolution date and MIKES.
