Thiencarbazone is a herbicide, as well as metabolite of relevant pesticides. | [Definition]
ChEBI: Thiencarbazone is an N-sulfonylurea in which the sulfur atom is attached to a 4-carboxy-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 metabolite of the herbicide, thiencarbazone-methyl. It has a role as a herbicide, an agrochemical, an EC 2.2.1.6 (acetolactate synthase) inhibitor and a metabolite. It is a thiophenecarboxylic acid, a N-sulfonylurea, an ether and a member of triazoles. | [Production Methods]
Industrial manufacture of thiencarbazone is normally as the methyl variant and generally follows a streamlined heterocycle-building sequence typical of modern sulfonylaminocarbonyl herbicides. Production begins with preparation of the key thiophene-based precursor, usually via acylation and cyclisation steps that introduce the substituted thiophene core. In parallel, the carbazone fragment is assembled through controlled reaction of a sulfonyl isocyanate or related activated carbonyl species with an appropriate amine, forming the sulfonylaminocarbonyl linkage that defines the class. These two fragments are then coupled under dehydrating or activating conditions to form the final heterocyclic urea-like structure. | [Mechanism of action]
