Chlorimuron-ethyl Chemical Properties,Uses,Production


Chlorimuron-ethyl is a kind of post-emergence, foliar applied herbicide which is used without the EU regulatory approval. As an herbicide belonging to the sulfonylurea family, it is commonly used to control the weeds associated with wheat, rice, soybean, barley, potato, and corn. It has advantages of being broad-spectrum, having low use rate, having good crop selectivity as well as being of low toxicity to animals. Its mechanism of action is through suppressing the plant- and microbial-specific enzyme acetolactate synthase (ALS), further blocking the biosynthesis of branched-chain amino acids such as valine, leucine and isoleucine. Through this mechanism, it cause rapid cessation of plant cell division and growth. 


Chemical Properties

Colorless to off white or pale yellow crystals or powder. Some formulations are listed as “flammable” in the literature. Odorless.



General Description

Colorless crystals. Used as an herbicide.

Reactivity Profile

Chlorimuron-ethyl is a sulfonyl urea, and pyrimidine derivative.

Agricultural Uses

Herbicide: Used to control broadleaf weeds and annual morning glory in soybeans and peanuts. Not listed as registered for use in EU countries. Registered for use in the U.S., except California. There are more than 25 global suppliers.

Potential Exposure

A sulfonylurea/pyrimidine derivative herbicide used to control broadleaf weeds and annual morning glory in soybeans and peanuts. Not listed as registered for use in EU countries. Registered for use in the United States and available from more than 25 global suppliers.

Metabolic pathway

Excised soybean seedlings rapidly metabolize 14C- chlorimuron ethyl, but common cocklebur and redroot pigweed, which are sensitive to chlorimuron ethyl, metabolize much more slowly. Two metabolites are primarily identified. By intact corn seedlings, chlorimuron ethyl undergoes biotransformation to give more metabolites and under UV light is photodegraded into smaller fragments.


UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.


Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, nitrates.

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
