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.

Tepraloxydim is a selective and systemic cyclohexanedione oxime herbicide. It is an acetyl CoA carboxylase (ACCase) inhibitor preventing the incorporation of acetate into fatty acids and blocking the production of phospholipids used in building new membranes. Tepraloxydim is used for post-emergence control of grass weeds, especially Poa annua, volunteer maize, Sorghum halepense, and Elymus repens, in broad-leaved crops, at 50–100 g/ha.
According to the Commission Implementing Regulation (EU) No 2022/801 of 20th May 2022, tepraloxydim is not approved for use as a plant protection agent in the European Union (EU), following the Regulation (EC) No. 1107/2009. But maximum residue levels of 0.1 mg/kg are allowed for the presence of tepraloxydim, measured as the sum of tepraloxydim and its metabolites that can be hydrolyzed either to the moiety 3-(tetrahydro-pyran-4-yl)-glutaric acid or to the moiety 3-hydroxy-(tetrahydro-pyran-4-yl)-glutaric acid, in products of plant and animal origin, according to the EU Reg. No 2019/91.
Tepraloxydim 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.
Tepraloxydim CRM may also be used as given below:

  • Screening and quantification of 569 pesticides in honeysuckle samples by a combination of ultrahigh-performance liquid chromatography (UHPLC) and quadrupole-Orbitrap high-resolution mass spectrometry
  • Detection of 252 pesticides extracted from surface water samples by solid-phase extraction (SPE) using liquid chromatography quadrupole-orbitrap high-resolution tandem mass spectrometry
  • Evaluation of 250 pesticide residues extracted by QuEChERS method from 103 processed fruit samples using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
  • Development of a method for simultaneous quantification of 200 pesticide residues in lettuce and orange samples based on methanol as the extraction solvent, ultra-high-performance liquid chromatography (UHPLC) for separation, and tandem mass spectrometry (MS/MS) for detection
  • Residue analysis of 261 pesticides, their metabolites, and polychlorinated biphenyls using modified QuEChERS protocol― optimized for extremely low molecular weight samples and liquid/gas chromatography coupled with tandem mass spectrometry
  • To develop and validate a method for the quantitative analysis of 207 pesticide residues in honey samples using both LC-MS/MS and GC-MS/MS compounds
