| Hazard Information | Back Directory | [Uses]
Insecticide for flies, roaches, and grain pests. | [Description]
Cyclethrin is a pyrethroid insecticide. Little data has been published on its environmental fate, ecotoxicology or its impact on human health. | [Production Methods]
The production of cyclethrin involves a multi-step organic synthesis centred around esterification and cyclopropane ring formation. The process begins with the preparation of a cyclopentenone derivative, which is then functionalised to introduce a cyclopent-2-en-1-yl group. Separately, a cyclopropane carboxylic acid derivative, typically bearing a 2-methylprop-1-enyl side chain, is synthesised, often using diazo compounds or Simmons–Smith-type reactions to construct the strained ring. These two key intermediates are then coupled via esterification, forming the final molecule. | [Mechanism of action]
Contact and stomach action. Sodium channel modulator. | [Pesticide Type]
