Hazard InformationBack Directory
[Chemical Properties]

Colorless crystalline solid or viscous yellowish-brown semisolid mass. Mild aromatic odor.
[Potential Exposure]

Pyrethroid Insecticide used for the control of a wide range of chewing and sucking insects (particularly lepidotera, coleoptera, and hemiptera) in fruit (including citrus), vegetables, vines, cereals, maize, beet, oilseed rape, potatoes, cotton, rice, soya beans, forestry, and other crops. Control of cockroaches, mosquitoes, flies, and other insect pests in public health; and flies in animal houses. Also used as an animal ectoparasiticide. zeta- Cypermethrin only is a United States Environmental Protection Agency Restricted Use Pesticide (RUP).

[Shipping]

UN3349 Pyrethroid pesticide, solid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous material. UN3352 Pyrethroid pesticide, liquid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
[Incompatibilities]

May react violently with strong oxidi- zers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders, or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate.
[Waste Disposal]

Do not discharge into drains or sewers. Burn in incinerator specifically designed for pes- ticide disposal or dispose as a Hazardous waste in a landfill approved and licensed for the disposal of pesticides. Consult with environmental regulatory agencies for guid- ance on acceptable disposal practices. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on ani- mal, aquatic, and plant life; and conformance with environ- mental and public health regulations.
[Uses]

(1R,2S,1''R)-Cypermethrin is used in the insecticidal activity of most active isomers of fenvalerate and other recent pyrethroids.
