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

Diafenthiuron, 1-tert-butyl-3-(2,6-di-isopropyl-4-phenoxyphenyl)thiourea, is an effective insecticide and acaricide. Sunlight degradation of diafenthiuron in various aqueous solutions and pure hexane yielded two major identified products: 1-tert-butyl-3-(2,6-di-isopropyl-4-phenoxyphenyl)-carbodiimide (CGA-140,408) and 1-tert-butyl-3-(2,6-di-isopropyl-4-phenoxy-phenyl)urea (CGA-177,960). CGA-140,408 was further photo-transformed into CGA-177,960 by sunlight. Direct photolysis appeared
