fluvalinate fluvalinate 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, infestations that constitute a significant disease of such insects. fluvalinateclinical dataahfs/drugs.cominternational drug namesatcvet codeqp53ac10 (who) identifiers iupac name 2--3-methylbutanoate cas number69409-94-5 n 102851-06-9 (tau-fluvalinate)pubchem cid50516chemspider45805 nunii364g5g03vckeggc10989 ychebichebi:5135chemblchembl3185183comptox dashboard (epa)dtxsid7024110 echa infocard100.233.047 chemical and physical dataformulac26h22clf3n2o3molar mass502.92 g·mol−13d model (jsmol)interactive image smiles cc(c)c(nc1ccc(c(f)(f)f)cc1cl)c(=o)oc(c#n)c1cccc(oc2ccccc2)c1 inchi inchi=1s/c26h22clf3n2o3/c1-16(2)24(32-22-12-11-18(14-21(22)27)26(28,29)30)25(33)35-23(15-31)17-7-6-10-20(13-17)34-19-8-4-3-5-9-19/h3-14,16,23-24,32h,1-2h3 nkey:inistdxbribgoc-uhfffaoysa-n n ny (what is this?) (verify) 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. stereoisomerism fluvalinate is synthesized from racemic valine , the synthesis is not diastereoselective. thus, fluvalinate is a mixture of four stereoisomers, each about 25%. fluvalinate stereoisomers (r,r)-configuration (s,s)-configuration (s,r)-configuration (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)-configuration (r,s)-configuration
