Disulfoton-sulfone is an oxidative metabolite of the organophosphorus insecticide disulfoton.
The European Union regulations define a maximum residue limit (MRL) of 0.01 mg/kg for disulfoton in foods of plant origin which is taken as a sum of disulfoton, disulfoton sulfoxide, and disulfoton sulfone. Currently, disulfoton is not allowed for its use in the European Union and also has restrictions over its use in the USA by American Environmental Protection Agency (EPA).
Application
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The disulfoton-sulfone CRM may also find given below uses:
Determination of disulfoton and its five metabolites in human blood and urine samples by QuEChERS extraction followed by liquid chromatography-tandem mass spectrometric analysis
Method development for the analysis of 15 organophosphorus pesticides and their metabolites in water samples using multiwalled carbon nanotubes based dispersive solid phase extraction and gas chromatography-nitrogen phosphorus detector (GC-NPD)
Simultaneous determination of 15 organophosphorus pesticides and their metabolites in cereal-based baby food samples using multi-walled carbon nanotubes based dispersive solid phase extraction and gas chromatography-nitrogen phosphorus detector (GC-NPD)
Analysis of 11 pesticides and 4 of their metabolites in chickpeas and barley flours using a modified QuEChERS extraction and GC-NPD determination
Multi-residue determination of 60 pesticides in hen egg samples by liquid-chromatography and gas chromatography with tandem mass spectrometry, in combination with QuEChERS based sample pre-treatment
Method development to quantify 49 organophosphorus pesticide residues and 10 of their metabolites in fish, egg, and milk samples by means of dual gas chromatography-dual pulse flame photometric detection
