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), that is 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, non-volatile[1], viscous heavy oil (technical) soluble in organic solvents.[2] Its effectiveness was first demonstrated in France and Israel.[when?][citation needed]

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.[3][better source needed]


Fluvalinate is synthesized from racemic valine [(RS)-valine], the synthesis is not diastereoselective. Thus, fluvinate is a mixture of four stereoisomers, each approx. 25 %.[4]


(4 stereoisomers)


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:[2]


(2 diastereomers)
