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%.{{cite book | vauthors = Whitacre DM |title=Reviews of environmental contamination and toxicology|publisher=Springer|page=125|isbn=978-1-4614-3280-7|date=2012|language=en|url={{Google books|L3gpxVLsbMYC&pg||page=125|plainurl=yes}}

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:
