一般描述

Diafenthiuron is classified under the thiourea family of insecticides which are widely used for crop protection.

应用

Diafenthiuron may be used as a reference standard for the analysis of diafenthiuron in:
  • Cotton and groundnut oil by quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction procedure, low-temperature freezing and dispersive clean-up followed by quantification using gas chromatography (GC) equipped with electron capture detector (ECD) as well as flame photometric detector (FPD) and liquid chromatography-tandem mass spectrometry (LC-MS/MS).
  • Tomatoes by QuEChERS extraction and LC combined with triple quadrupole MS/MS with electrospray ionization source (ESI).
  • Fruit juice samples by ionic liquid-assisted liquid-phase microextraction based on the solidification of floating organic droplets (ILSFOD-LLME) and high performance liquid chromatography (HPLC) equipped with a variable-wavelength detector (VWD).
  • Water and wastewater by solid phase extraction (SPE) and LC combined with time-of-flight (TOF) MS.

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