Electron ionisation mass spectral analysis and fragmentation pathways for some thiophosphorylic p-carboxybenzene sulfonamides.
The work presents the 70 eV electron impact mass spectra of some thiophosphorylic p-carboxybenzene sulfonamides, and proposes rationalisation of their fragmentation pathways. Accurate mass measurements of the fragment ions, and metastable ion analyses performed in the MIKES mode, were used to elucidate the most abundant ion compositions and to elucidate the fragmentation patterns of these pharmacologically interesting compounds.
