Quizalofop-ethyl Chemical Properties,Uses,Production

Chemical Properties

White crystalline solid or powder. Commercial product is available as an emulsifiable con- centrate. Practically insoluble in water; solubili- ty≤2×10-28 ppm.




Quizalofop-ethyl is a selective postemergence herbicide used to control both annual and perennial grasses in soybeans and cotton.

General Description

White crystals. Insoluble in water. Used as an herbicide.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

A halogenated ester and amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Agricultural Uses

Herbicide: Not approved for use in EU countries. Registered for use in the U.S.

Potential Exposure

A chlorophenoxy/aryloxyphenoxypro- pionate herbicide

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions) if breathing has stopped, and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Do not induce vomiting when formulations containing petroleum solvents are ingested. Otherwise, give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Environmental Fate

Plant. Rapidly hydrolyzed in plants to quizalofop and ethanol (Humburg et al., 1989).


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

Purification Methods

This (±)-herbicide forms white crystals from Me2CO/EtOH and sublimes in vacuo. Large quantities can be distilled at high vacuum. Its solubilities at 20o in g/10mL are 0.09 (EtOH), 1.1 (Me2CO), 1.2 (xylene), 2.9 (*C6H6), and is nearly insoluble in H2O (0.3mg/L). The (±)-acid has [95977-28-9]. The R-ester enantiomer has m 76-77o (pale brown crystals from EtOH), [ ] D 20 + 3 5 . 9o (EtOH). It is the more active fatty acid synthase inhibitor (designated DPX-Y6202) used to control grassy weeds in broadleaf crops.

Waste Disposal

It is the responsibility of chem- ical waste generators to determine the toxicity and physical properties and of a discarded chemical and to properly iden- tify its classification and certification as a hazardous waste and to determine the disposal method. United States Environmental Protection Agency guidelines for the classifi- cation determination are listed in 40 CFR Parts 261.3. In addi- tion, waste generators must consult and follow all regional, national, state, and local hazardous waste laws to ensure com- plete and accurate classification and disposal methods.
