ABSTRACT:

A series of organophosphorus compounds related to PB-1 toxin [O,O-diphenyl N-cyclooctylphosphoramidate] occurring in dinoflagellate algae as fish toxin have been synthesized and subjected to mass spectral studies under electron ionization. The fragmentation pattern obtained for the compounds has been substantiated by performing tandem mass spectrometry experiments in product ion scan mode.

Keywords: organophosphorus, PB-1, dinoflagellate algae, electron ionization, mass spectral studies, tandem mass spectrometry, fragmentation
