Tribenuron-methyl
Tribenuron in the form of tribenuron-methyl is a sulfonylurea herbicide. Its mode of action is the inhibition of acetolactate synthase, group 2 of the Herbicide Resistance Action Committee's classification scheme. Chemistry In the 1970s, chemists at DuPont worked extensively on sulfonylurea herbicides, following the invention of this class of herbicides by George Levitt which had led to the commercialisation of chlorsulfuron. Tribenuron (the carboxylic acid) and its methyl ester were first disclosed in general terms in one of Levitt's patents and subsequently the ester was subject to further patenting and selected for development under the code name DPX L5300. In the final step of its synthesis, 2-methoxycarbonylbenzenesulfonyl isocyanate was condensed with 2-methylamino-4-methoxy-6-methyl-1,3,5-triazine to form the sulfonylurea product. : Mode of action Tribenuron is an herbicide that acts as an acetolactate synthase inhibitor.
