| Cyhalothrin Usage And Synthesis |
| Uses | Insecticide; acaricide. | | 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. | | 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 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). |
