Description:

Sulfonylurea herbicides have been studied using neg-ion desorption chem.-ionization (DCI) mass spectrometry (MS) and DCI-MS/MS techniques. Both {M-H]- and M.- ions were obsd. in the DCI mass spectra. The collisonally activated dissocn. (CAD) spectra were characteristic of the structure of the herbicides examd. The fragmentation pattern was established based on the tandem mass spectra of the in situ deuterated sulfonylureas and on the comparison of the CAD spectra of sulfonylurea fragment ions with the CAD spectra of the ions derived from saccharin and Me2-(aminosulfonyl)benzoate.
