| The conversion of several sulfonylurea herbicides such as thifensulfuron methyl (1) to their respective dimethyl derivatives has resulted in the reduction of molecular polarity. These derivatives which have been characterized by NMR, mass spectra, and elemental analysis form the basis of an efficient gas chromatographic method for the analysis of parent sulfonylureas. Electron capture (EC), nitrogen phosphorous (NP), and mass selective (MS) detectors are the suitable detecting devices for these analyses.
