Fluvalinate

Fluvalinate is considered an acute toxic, health hazard and environmental hazard by ECHA (European Chemicals Agency). The chemical is fatal if inhaled and is extremely toxic to aquatic life. Hazard codes indicate fluvalinate is both an acute and long-term toxic hazard in aquatic systems. It is considered a developmental hazard though there are no established chronic effects in adult humans. Fluvalinate can be found in both honey and beeswax though it tends to migrate to beeswax over time due to its lipophilic nature. Pesticide products containing fluvalinate have been banned in Denmark because the chemical can degrade into trifluoroacetic acid, which can then contaminate groundwater and not decompose. == 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%. 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: == See also ==
