A rapid, sensitive method is described for the determination of 5-(methylamino)-2-phenyl-4-(3-(trifluromethyl)phenyl)-3-(2H)-furanone (RE-40885) concentrations in three soil types. The method consists of extraction of soil samples with methanol, filtration, liquid chromatographic separation of methanol-soluble components using a C18 column and UV detection at 275 nm. Recoveries were 94, 96, and 94% from the Greenville, Cecil, and Dothan soils, respectively. Average relative standard deviation was 8.0% in the Greenville soil. The qualitative limit of detection was 20 ppb and the limit of quantitation was 40 ppb in 25-g soil samples.
