Chemistry
Flumethrin is a complex mixture of stereoisomers. The molecule contains three asymmetric carbon atoms, there is cis-trans isomerism at the cyclopropane ring, and E/Z isomerism at the carbon-carbon double bond of the alkene. So there are 16 different isomers. Commercial flumethrin typically contains 92% of the trans isomers on the cyclopropane ring and the Z configuration at the olefinic carbon-carbon double bond and 8% of the isomer with cis geometry on the cyclopropane ring and the Z configuration at the olefinic carbon-carbon double bond.[3]
Uses
Flumethrin is used in products, such as flea and tick collars, to protect pets against fleas.[4]
It is also used in the proprietary product, ″Bayvarol″, ″Polyvar Yellow″ which are veterinary treatments used by beekeepers against the parasitic mite Varroa destructor.
