| Hazard Information | Back Directory | [Chemical Properties]
This product is a systemic, selective, post-emergence herbicide. After application, it is absorbed by the leaves and roots of weeds and rapidly transported throughout the body, inhibiting cell division, halting weed growth, and gradually killing the weeds. It is used to control annual broadleaf weeds in wheat fields, requiring minimal dosage and offering safe and effective results. It decomposes rapidly in the soil and has no effect on the next crop 30 days after application. | [Uses]
Thifensulfuron is used as a herbicide, a chemical compound that function by inhibiting the action of a plant enzyme, stopping plant growth, and eventually killing the plant. | [Definition]
ChEBI: An N-sulfonylurea in which the sulfur atom is attached to a 2-carboxythiophen-3-yl group and in which the non-sulfonated nitrogen is substituted by a 4-methoxy-6-methyl-1,3,5-triazin-2-yl group. The corresponding methyl ester, known as t
ifensulfuron-methyl, is used as a post-emergence herbicide for the control of grass and broad-leaved weeds. | [Production Methods]
Thifensulfuron is commercially produced through a multi-step synthesis that begins with the preparation of two key intermediates: a methoxy-substituted triazine and a thiophene carboxylic acid derivative. The process involves the nucleophilic substitution of a 2-chloro-4-methoxy-6-methyl-1,3,5-triazine with sulfamoyl isocyanate, followed by coupling with 3-amino-2-thiophenecarboxylic acid to form the sulfonylurea bridge. This reaction is typically carried out in polar aprotic solvents under controlled pH and temperature to ensure high selectivity and yield. | [Mechanism of action]
Selective, absorbed through foliage. Inhibits plant amino acid synthesis - acetohydroxyacid synthase AHAS | [Pesticide Type]
