Definition

ChEBI: Triflusulfuron-methyl is a methyl ester resulting from the formal condensation of the carboxy group of triflusulfuron with methanol. A proherbicide for triflusulfuron. It has a role as a proherbicide, an agrochemical and an EC 2.2.1.6 (acetolactate synthase) inhibitor. It is a benzoate ester, a methyl ester, a N-sulfonylurea, a member of 1,3,5-triazines, a tertiary amino compound, an aromatic ether and an organofluorine compound. It is functionally related to a triflusulfuron.
