Methiocarb sulfone is a carbamate pesticide and one of the four metabolites of insecticide, molluscicide, and bird-repellent methiocarb.
As per the commission implementing regulation (EU) 2019/1606 of 27^th September 2019, methiocarb (expressed as the sum of methiocarb, methiocarb sulfone, and methiocarb sulfoxide) is not approved for use in the European Union. Maximum residue levels (MRLs) have been set according to Reg (EC) No 149/2008 for methiocarb (expressed as the sum of methiocarb, methiocarb sulfone, and methiocarb sulfoxide) for various products of plant and animal origin from 0.01 to 0.1 mg/kg. Methiocarb has to be monitored in the Multiannual Control Program for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The methiocarb sulfone CRM may also find following uses:

• Method development for simultaneous determination of methiocarb, methiocarb sulfoxide, and methiocarb sulfone in five food products of animal origin (milk, chicken, pork, beef, and eggs) by liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Determination of 304 pesticide residues in citrus fruit (grapefruit, lemon, orange and mandarin) and vegetable (cucumber, eggplant, tomato and zucchini) samples by liquid chromatography-tandem mass spectroscopy (LC-MS/MS)
• Analysis of environmental water samples for the presence of 23 carbamate pesticide residues by solid-phase extraction (SPE) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
• Develop a UHPLC-MS/MS method to determine 28 carbamate pesticide residues in fresh herb samples of basil, spearmint, wild mint, parsley, Chinese parsley, thyme, chives, and salvia after their QuEChERS-based extraction
• Validation of a method based on QuEChERS extraction and LC-MS/MS and GC-MS/MS quantification of 218 pesticide residues in clay loam soil
• Multi-residue analysis of pesticides and mycotoxins in red wine using direct injection for sample preparation and UPLC-MS/MS for analysis
• Method development for detection and quantification of 260 pesticides and mycotoxins in green tea and royal jelly nutraceutical products by “dilute and shoot” extraction procedure and quantification by LC-Orbitrap-MS
