Chiral stability of synthetic pyrethroid insecticides

Synthetic pyrethroids are chiral compounds consisting of multiple stereoisomers. Evaluation of enantioselectivity in environmental fate and ecotoxicity requires analytical methods that preserve stereoisomer integrity during analysis. In this study, we characterized the stability of stereoisomers from four commonly used pyrethroids, cis-bifenthrin (cis-BF), permethrin (PM), cypermethrin (CP), and cyfluthrin (CF), during gas chromatography (GC) analysis and sample preparation. Stereoisomers of cis-BF and PM were found to be stable, but those of CP and CF were unstable, under heat or in water. Isomer conversion occurred only at the aC in CP or CF, causing the analyte stereoisomer to convert to an epimer. At a GC inlet temperature of 260°C, about 9% conversion occurred for CP and CF. In organic solvents and sterile water, stereoisomers of cis-BF and PM were stable, but slow isomer conversion was observed for CP and CF in water at ambient temperature. However, isomer conversion for CP and CF was relatively insignificant (2-3%) when the GC inlet temperature was kept at ≤ 180°C or when on-column injection was used. Isomer conversion at the αC in water suggests that abiotic processes may also contribute to enantioselectivity observed in the environment for pyrethroids with the asymmetric αC.

Wood preservatives

Wood preservatives having biocidal properties which include quaternary ammonium compounds of general formula (I): wherein R1 is a C8-18-alkyl group or an optionally substituted benzyl group, R2 is a C8-18-alkyl group, R3 is a C1-4-alkyl group or a group of the formula —[CH2—CH2—O]n—H, R4 is a C1-4-alkyl group, n is a number from 0.5 to 8, preferably from 1 to 5, and A?is the anion of an organic carboxylic acid which contains 2 to 12 C atoms and carries at least one hydroxyl, amino or sulfonic acid group. The wood preservatives also penetrate deeply into the wood without the use of pressure, and have only a mild corrosive action on metals. Furthermore, a process for treating timbers with these compositions, concentrates for the preparation thereof, the use of new and known quaternary ammonium compounds in wood preservatives and new quaternary ammonium compounds and their use as biocides.

Anti-fouling compositions

An anti-fouling composition comprising a carrier, and a binder, the improvement which comprises an effective amount of at least one insecticide. The composition is applied to the surfaces of articles which come into contact with seawater or brackish water, especially wood. Other conventional anti-fouling agents may also be present.
