Ethiofencarb sulfone is a metabolite of the carbamate insecticide, ethiofencarb, and an acetylcholinesterase inhibitor.
Its parent, ethiofencarb is not allowed for use in the European Union as per the commission regulation no 1107/2009, regarding the use of plant protection products and repealing the council directive 91/414/EEC.
Application
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
It can also be used as follows:

Monitoring of carbamate insecticides and their metabolites in green sea turtles on the Great Barrier Reef by Ultra high-performance liquid chromatography coupled to mass spectrometry
Multi-residue analysis of 250 pesticides by ultra-performance liquid chromatography (UHPLC) coupled to MS/MS in processed fruits
Simultaneous determination of 74 pesticide residues in orange juice samples using an optimized QuEChERS extraction and UHPLC-MS/MS
Development and validation of a UHPLC-MS/MS based method for the quantification of 31 carbamate pesticide residues in five different edible oil samples
Quantification of 166 pesticides at low ppb concentrations levels using UHPLC and electrospray ionization quadrupole Orbitrap high-resolution mass spectrometry (ESI Q-Orbitrap) along with QuECHERs in fruits and vegetables
Determination of 25 carbamate pesticide residues in different wine varieties using UHPLC-MS/MS for separation and detection and ultrasound-assisted surfactant-enhanced emulsification microextraction (UASEME) for sample treatment
