1R-cis-Bifenthrin is a synthetic pyrethroid broadly used as a pesticide for pest and insects control. | [Definition]
ChEBI: Bifenthrin is a carboxylic ester obtained by formal condensation of cis-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethylcyclopropanecarboxylic acid and [(2-methyl-1,1'-biphenyl)-3-yl]methanol. It has a role as a pyrethroid ester insecticide and a pyrethroid ester acaricide. It is an organochlorine compound, an organofluorine compound and a cyclopropanecarboxylate ester. It is functionally related to a cis-chrysanthemic acid. | [Production Methods]
Kappa bifenthrin is not manufactured through a unique process of its own; it is the stereochemically enriched isomer of bifenthrin, so its production follows the same broad sequence used for bifenthrin technical material. Bifenthrin is synthesised through a multi-step process that constructs its pyrethroid ester structure without the use of solvents, enhancing both efficiency and environmental safety. The production begins by mixing 2-methyl-3-phenylbenzyl alcohol with a catalyst in a reaction vessel and heating until molten. Then, 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropane methyl halide is added dropwise under negative pressure. Kappa bifenthrin is obtained by post reaction isomer separation or enrichment. | [Mechanism of action]
