Fluvalinate^[1] is a synthetic pyrethroid chemical compound contained as an active agent in the products Apistan,^[2] Klartan, and Minadox, that is an acaricide (specifically, a miticide), commonly used to control Varroa mites in honey bee colonies,^{[citation needed]} infestations that constitute a significant disease of such insects.

Fluvalinate is a stable, nonvolatile,^[3] viscous, heavy oil (technical) soluble in organic solvents.^[4] 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.^[5]^{[better source needed]}

CHS Health Classification

Fluvalinate is considered an acute toxic, Health hazard and environmental hazard by ECHA (European Chemicals Agency).

The chemical is fatal if inhaled and is extremally toxic to aquatic life. If not fatal the effects are permanent and has multiple long lasting effects.

Stereoisomerism

Fluvalinate is synthesized from racemic valine [(RS)-valine], the synthesis is not diastereoselective. Thus, fluvalinate is a mixture of four stereoisomers, each about 25%.^[6]

Tau-fluvalinate (τ-fluvalinate) is the trivial name for (2R)-fluvalinate. The C atom in the valinate structure is in (R)-absolute configuration, while the second chiral atom is a mixture of (R)- and (S)-configurations:^[4]
