General description

Coumatetralyl is classified under the hydroxycoumarin group of anticoagulant rodenticides.

Application

Coumatetralyl may be used as an analytical reference standard for the determination of coumatetralyl in:
  • Sludge samples by solid-liquid extraction (SLE) and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) equipped with electrospray ionization (ESI), and selected reaction monitoring (SRM) detection.
  • Wastewater samples by miniaturized liquid-liquid extraction (LLE), solid-phase extraction (SPE) and LC-ESI-MS/MS with SRM detection.
  • Vertebrate wildlife and domestic animals by gel permeation chromatography (GPC) clean-up followed by ultra-high performance liquid chromatography (UHPLC) coupled to ESI-MS/MS with multiple reaction monitoring (MRM) detection.
  • Blood samples by LLE and ESI-LC-MS/MS with MRM detection.
