Fenthion oxon sulfoxide

Application
Fenthion oxon sulfoxide may be used as a reference standard in the determination of fenthion oxon sulfoxide in water samples using:
Liquid chromatography coupled with triple quadrupole mass spectrometry (LC–QqQ-MS) and liquid chromatography coupled with hybrid quadrupole time-of-flight mass spectrometry(LC–QTOF-MS).[1] High performance liquid chromatography with diode array detection (HPLC-DAD) and atmospheric pressure chemical ionization mass spectrometric detection (HPLC-APCI).[2]

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
General description
Fenthion oxon sulfoxide is a metabolite of fenthion, obtained by oxidative desulfuration. It is widely used as a pesticide in controlling insects in numerous crops.[1] Its mode of action involves the inhibition of acetylcholinesterase.[1] Other Notes
