General description
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.

Clofentezine is a tetrazine group containing insecticide used against phytophagous mites on citrus fruits, vines, cotton crops, and ornamentals.
As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, clofentezine is approved for plant protection use in the European Union (EU). A maximum residue limit (MRL) of 0.5 mg/kg and 0.05 mg/kg is applicable for the presence of clofentezine in fresh/frozen fruits and tree nuts respectively, in accordance with Regulation (EC) No. 2015/846. Clofentezine is 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.
- The clofentezine CRM may also find following uses:
- Development and validation of a high-performance liquid chromatography-diode-array detection (HPLC-DAD) method following a dispersive solid phase extraction using zirconia-coated silica particles for the analysis of 21 pesticide residues in oil samples
- Development of a sample preparation method based on magnetic mixed hemimicelles dispersive solid-phase extraction (MMHDSPE) to separate three acaricides from three fruit juice samples
- Multi-residue determination of 60 pesticide residues in hen eggs using QuEChERS extraction followed by an LC-MS/MS or GC-MS/MS quantification
- Simultaneous analysis of 302 pesticides and contaminants in ten catfish samples by low-pressure GC-MS/MS and UHPLC-MS/MS
- GC-MS/MS and LC-MS/MS based determination of 314 pesticide residues in raisin samples for their risk exposure assessment
- Simultaneous analysis of 300 pesticide residues in human hair samples by GC-MS/MS and LC-MS/MS
