Methabenzthiazuron is a broad-spectrum phenylurea herbicide that binds to the Q_B site of the D1 protein of the photosystem II complex and inhibits the photosynthetic electron transport. It is a selective herbicide, absorbed primarily through roots and to a lesser extent by leaves. It is used to control broad-leaved and grass weeds in cereals, legumes, maize, garlic, and onions.
According to the Commission Implementing Regulation (EU) No 2006/302, methabenzthiazuron is not approved for use in the European Union (EU) as a plant protection agent, following the Regulation (EC) No. 1107/2009.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Methabenzthiazuron CRM may also be used in method development and validation to determine:

• 275 pesticides and their metabolites in surface water samples by reversed-phase liquid chromatography (LC)-Orbitrap high-resolution mass spectrometry (HRMS) following their solid-phase extraction (SPE), using hydrophilic-lipophilic balanced polymeric sorbents (HLB)
• 379 pesticides in human serum samples extracted by QuEChERS method using liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• 34 of triazine, phenylurea, triazole, and neonicotinoid pesticides in five agricultural soil samples by liquid chromatography-high resolution quadrupole time-of-flight mass spectrometry (LC-QTOF-MS)
• 260 pesticides in human urine samples using liquid chromatography-tandem mass spectrometry (LC-MS/MS) with rapid switching between positive and negative electrospray ionization (ESI) modes
• 250 pesticide residues extracted by QuEChERS method from 103 processed fruit samples using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
• 327 multiclass pesticide and 17 veterinary drug residues in eight animal feed samples using liquid- and gas- chromatography combined with tandem mass spectrometry (LC-MS/MS and GC-MS/MS)
