A racemate comprising equimolar amounts of (R)- and (S)-cyflumetofen. A proacaricide (via ester hydrolysis and subsequent decarboxylation), it is used to control phytophagous mites at all development stages in a variety of fruit crops. It acts as an inhibitor of complex II of mitochondrial electron transport chain. ChEBI: 2-methoxyethyl 2-(4-tert-butylphenyl)-2-cyano-3-oxo-3-[2-(trifluoromethyl)phenyl]propanoate is a nitrile that is acetonitrile in which the methyl hydrogens have been replaced by o-trifluoromethylbenzoyl, p-tert-butylphenyl, and (2-methoxyethoxy)carbonyl groups. It is a nitrile, a beta-ketoester, a member of (trifluoromethyl)benzenes and a 2-methoxyethyl ester.
