General description

Azinphos-ethyl is classified under the organophosphorus family of insecticides.

Application

Azinphos-ethyl may be used as a reference standard for the determination of azinphos-ethyl in:
  • Water samples by solid phase extraction (SPE) and ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QqTOF-MS).
  • Cereals by QuEChERS (quick, easy, cheap, effective, rugged, and safe) extraction and gas chromatography-triple quadrupole mass spectrometry (GC-QqQ MS/MS).
  • Fruits and vegetables and neutraceuticals derived from grape seed extracts by QuEChERS extraction and UHPLC-QqQ MS/MS with electrospray ionization (ESI) source and multiple reaction monitoring (MRM) mode of detection.
  • Seawater samples by SPE and LC-ESI-MS/MS.

Ethylazinphos increases the passive proton permeability of lipid bilayers reconstituted with dipalmitoylphosphatidylcholine (DPPC) and mitochondrial lipids. A sharp increase of proton permeability is detected at insecticide/lipid molar ratios identical to those inducing phase separation in the plane of DPPC bilayers
