General description

Diazinon-(diethyl-d10) is an isotope labeled analog of the organophosphate pesticide diazinon, wherein the diethoxy protons are replaced by deuterium.

Application

Diazinon-(diethyl-d10) may be used as an internal standard for the determination of diazinon in soybeans and Daphnia magna by various chromatography techniques.
Isotope-labeled compounds are increasingly used in isotope dilution mass spectrometry (IDMS) for the quantitative analysis of pesticides. The major advantage of using this technique is that the isotope-labeled compounds have nearly the same physical properties as their non-labeled counterpart analogs, and thus show identical behavior during the workup and sample preparation process. This helps in overcoming the problems of matrix effects generally encountered in the usual LC-MS/GC-MS analysis, potentially resulting in biased results. By spiking the sample before workup with its isotope labeled analog, the loss of analyte that leads to matrix effects can be determined and compensated.
