Thiencarbazone-methyl Chemical Properties,Usage,Production

Uses

Thiencarbazone is a herbicide, as well as metabolite of relevant pesticides.

Definition

ChEBI: Thiencarbazone-methyl is an N-sulfonylurea in which the sulfur atom is attached to a 4-(methoxycarbonyl)-2-methylthiophen-3-yl group and in which the non-sulfonated nitrogen is substituted by a 3-methoxy-4-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl group. It is a herbicide used for the selective control of grasses and broadleaf weeds primarily in corn. It has a role as an EC 2.2.1.6 (acetolactate synthase) inhibitor, a herbicide and an agrochemical. It is a member of thiophenes, a methyl ester, a member of triazoles, a N-sulfonylurea and an ether. It is functionally related to a thiencarbazone.
