Fluvalinate is a synthetic pyrethroid chemical compound contained as an active agent in the products Apistan, Klartan, and Minadox, that is an acaricide (specifically, a miticide), commonly used to control Varroa mites in honey bee colonies,Шаблон:Cn infestations that constitute a significant disease of such insects.

Fluvalinate is a stable, nonvolatile, viscous, heavy oil (technical) 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.Шаблон:Better source

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%.

Fluvalinate stereoisomers
(R,R)-Fluvalinat (R,R)-configuration
(S,S)-Fluvalinat (S,S)-configuration
(S,R)-Fluvalinat (S,R)-configuration
(R,S)-Fluvalinat (R,S)-configuration

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:

τ-Fluvalinate diastereomers
(R,R)-Fluvalinat (R,R)-configuration
(R,S)-Fluvalinat (R,S)-configuration
