General description

Isopyrazams are categorized under the class of succinate-dehydrogenase-inhibitor (SDHI) fungicides that are applied on a variety of fruits and vegetables.

Application

Isopyrazam may be used as an analytical reference standard for the determination of the analyte in:
  • Honeybees by dispersive solid-phase extraction (dSPE), followed by liquid and gas chromatography combined with tandem mass spectrometry (LC-MS/MS and GC-MS/MS) operating in electron ionization (EI) and multiple reaction monitoring (MRM) modes of detection.
  • Bee pollen samples by GC-MS/MS in single reaction monitoring (SRM) mode of detection.
