Metrafenone is a systemic fungicide used for its protective, curative, and anti-sporulant properties. It belongs to the chemical class of benzophenones and is used against Pseudocercosporella herpotrichoides and Erysiphe graminis in winter and spring wheat, and barley and Uncinula necator in grapes.
According to the Commission Implementing Regulation (EU) No 540/2011 of 25th May 2011, metrafenone is approved for use in the European Union (EU) as an active substance in plant protection products, following the Regulation (EC) No. 1107/2009. Maximum residue levels (MRLs) of 0.01 mg/kg to 7 mg/kg are set for the presence of metrafenone in products of plant and animal origin, according to the EU Reg. No 2018/687.
Metrafenone has to be monitored in the Multiannual Control Programme for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Metrafenone CRM may also be used in the residue analysis of:

• 209 pesticides and persistent organic pollutants (POPs), extracted by QuEChERS-based procedure from fresh bovine and chicken liver samples, using gas chromatography coupled to tandem mass spectrometry (GC-MS/MS)
• 252 pesticides extracted from surface water samples by solid-phase extraction (SPE) using liquid chromatography quadrupole-orbitrap high-resolution tandem mass spectrometry
• 250 pesticide residues extracted by QuEChERS method from 103 processed fruit samples using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
• 379 pesticides in human serum samples extracted by QuEChERS method using liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Metrafenone in nine fresh vegetable samples using matrix solid-phase dispersion (MSPD) and HPLC-UV
• Metrafenone in bitter gourd and soil samples using gas chromatography combined with an electron capture detector (GC-ECD)
