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 a sulfamoylbenzoate, a N-sulfonylurea, an aromatic ether, an ethyl ester, an organochlorine pesticide and a member of pyrimidines. It derives from a chlorimuron. It is a conjugate acid of a chlorimuron-ethyl(1-).
