| Hazard Information | Back Directory | [Uses]
trans-Permethrin is the trans isomer of Permethrin (P288500) which is a common synthetic pyrethoid insecticide with low mammalian toxicity. | [Production Methods]
Trans-permethrin is produced through an esterification reaction between 3-phenoxybenzyl alcohol and (1R, trans)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid, which is the trans-configured acid component. The synthesis begins with the preparation of the cyclopropane acid via cyclopropanation and chlorination, ensuring the correct trans stereochemistry. Separately, the alcohol is synthesised from 3-phenoxybenzaldehyde through reduction. These two components are then combined under controlled conditions to form the ester bond. Since permethrin consists of a mixture of cis and trans isomers, purification techniques such as recrystallisation or chromatographic separation are employed to isolate the trans isomer. This | [Mechanism of action]
Neurotoxin, acts on the nervous system of insects, and disturbs the function of neurons by interaction with the sodium channel. | [Safety Profile]
A poison by intravenous route. Moderately toxic by intraperitoneal route. Questionable carcinogen. When heated to decomposition it emits toxic vapors of Clí. | [Pesticide Type]
Insecticide; Veterinary substance |
