Polypyrrole‐coated rubber foam sorbent for extraction of fipronil and fipronil sulfone in tea

SEPARATION SCIENCE PLUS, 2023
Abstract A polypyrrole‐coated rubber foam sorbent with a steel wire insert was developed for the magnetic solid phase extraction of fipronil and fipronil sulfone from tea samples for analysis by a gas chromatography‐electron capture detector.

Recent advances on the influence of fipronil on insect behavior.

Current Opinion in Insect Science
Fipronil, a pesticide widely used to control agricultural and household insect pests, blocks insect GABAA and glutamate (GluCl) ionotropic receptors, resulting in uncontrolled hyperexcitation and paralysis that eventually leads to death.

Elucidation of Fipronil Photodegradation Pathways

Journal of Agricultural and Food Chemistry, 2000
The phenylpyrazole insecticide fipronil (I) photolyzes to its desthio product (II) in aqueous solution. However, the necessity of an intervening oxidation to a sulfone intermediate (III) has not been resolved, and the photodegradation products of II have not been identified.

Analytical Method for Fipronil and Fipronil Sulfone in Livestock Products Using LC-MS/MS

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 2020
A rapid and sensitive method for the simultaneous determination of fipronil and fipronil sulfone (metabolite B) in livestock products was developed. The analytes were extracted from samples with acidic acetonitrile. The crude extracts were subjected to clean-up step using neutral alumina cartridge column.

P-coumaric acid ameliorates fipronil induced liver injury in mice through attenuation of structural changes, oxidative stress and inflammation.

Pesticide Biochemistry and Physiology, 2021
Fipronil is a broad-spectrum phenylpyrazole insecticide and has been used effectively in the agriculture. Due to its widespread use and bioaccumulation in the environment, it possesses significant threat to human and animals. P-coumaric acid is a natural

Rapid and Sensitive Quantitation of Fipronil and Its Metabolites Fipronil Sulfone, Fipronil Sulfide, and Fipronil Desulfinyl in Zebrafish Tissues by UHPLC‐MS/MS

Journal of Separation Science
ABSTRACT An ultra‐high performance liquid chromatography‐tandem mass spectrometry (UHPLC‐MS/MS) method was developed and validated for the simultaneous determination of fipronil and its three metabolites (fipronil sulfone, fipronil sulfide, and fipronil desulfinyl) in zebrafish tissues.

Synthesis of fipronil sulfide, an active metabolite, from the parent insecticide fipronil

Tetrahedron Letters, 2001
Abstract A convenient procedure for the synthesis of fipronil sulfide, one of several active metabolites identified from the insecticide fipronil, has been developed. Reduction of fipronil with trifluoroacetic anhydride–sodium iodide in acetone, followed by flash chromatography afforded fipronil sulfide in 60% yield and >99.9 percent purity.

Sorption and Desorption of Fipronil in Midwestern Soils

Bulletin of Environmental Contamination and Toxicology, 2009
Fipronil, {5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile} is commonly applied to soil to protect structures against termite infestations. The fate and bioavailability of fipronil in soil is dependent upon the variability of sorption processes and will differ from soil to soil.
