Application

Prallethrin may be used as an analytical reference standard for the determination of the analyte in:
  • Sediment samples by dichloromethane (DMC)-based Soxhlet extraction and high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS).
  • Domestic wastewater samples by ultrasound-assisted dispersive liquid–liquid microextraction (UA-DLLME) combined with capillary GC.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

General description

Prallethrins are classified under the broad category of pyrethroid insecticides that are utilized in agricultural, domestic and industrial applications. They are typically used for protection against mosquitoes, cockroaches as well as other insects.

1. Two major metabolites of 14C-labelled (4S,1R)-trans-Etoc[(S)-2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl (1R)-trans-chrysanthemate] were purified using a combination of chromatographic techniques and identified by spectroanalysis (nmr(HMBC) and FAB-, TSP-MS). These were established as new types of S-linked conjugates (sulphonic acid and mercapturic acid types). 2.
