Hazard Information

Uses

Cyhalothrin is used mainly for ectoparasite control on animals. Lambda-cyhalothrin has public health use and is also used for the control of a variety of insect pests in potatoes (Colorado beetle), cereals, hops, vegetables, cotton and other crops.

Uses

Insecticide; acaricide.

Definition

ChEBI: A carboxylic ester obtained by formal condensation between 3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylic acid and cyano(3-phenoxyphenyl)methanol.

General Description

Colorless solid. Insoluble in water. Used as a wide spectrum insecticide.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Cyhalothrin(68085-85-8) is a trifluoromethyl pyrethrine derivative.

Metabolic pathway

Cyhalothrin is similar in structure to cypermethrin but with one of the chlorine atoms replaced by a trifluoromethyl group. This substitution appears to result in greater lipophilicity. Cyhalothrin is used in animal health and the more active isomer mixture, lambda-cyhalothrin, has the main crop use. Only a limited amount of information has been published in the scientific literature. What is available indicates that the metabolism and environmental fate of the cyhalothrins are very similar to those of cypermethrin. Both compounds have been the subject of UK Pesticide Safety Directorate evaluations (referred to as PSD in parentheses below).

Degradation

Cyhalothrin is stable to decomposition and to cis-trans isomerisation for at least 4 years in the dark. It is a photostable pyrethroid. It is hydrolysed at high pH to afford the acid (2) and the cyanohydrin (3) which decomposes to 3-phenoxybenzaldehyde (4,3PBAl).
