Fluvalinate
Fluvalinate is a synthetic pyrethroid chemical compound contained as an active agent in the products Apistan, Klartan, and Minadox, that is an acaricide, commonly used to control Varroa mites in honey bee colonies, infestations that constitute a significant disease of such insects.
Fluvalinate is a stable, nonvolatile, viscous, heavy oil soluble in organic solvents.
Although the compound may be found in drones, a study has found honey samples virtually absent of fluvalinate, on account of its affinity to beeswax.
Stereoisomerism
Fluvalinate is synthesized from racemic valine , the synthesis is not diastereoselective. Thus, fluvalinate is a mixture of four stereoisomers, each about 25%.| Fluvalinate stereoisomers |
