Chlorimuron-ethyl is an ethyl ester resulting from the formal condensation of the carboxy group of chlorimuron with ethanol. A proherbicide for chloimuron, it is used as herbicide for the control of broad-leaved weeds in peanuts, soya beans, and other crops. It has a role as a proherbicide, an EC 2.2.1.6 (acetolactate synthase) inhibitor and an agrochemical. It is an ethyl ester, an aromatic ether, an organochlorine pesticide, a member of pyrimidines, a sulfamoylbenzoate and a N-sulfonylurea. It is functionally related to a chlorimuron. It is a conjugate acid of a chlorimuron-ethyl(1-).
