| Abstract: | The triazinone herbicides metamitron and metribuzin are degraded by desamination. After a derivatization step with ethereal diazomethane solution, different structures of the metabolites were determined by GC/MS. The assumption that this is based on a ketoenol-tautomery was confirmed by GC/FTIR and 1H-NMR spectroscopy. This fact has to be considered for carrying out definite metabolite identification. |
