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.

Ethalfluralin is a pre-plant soil applied herbicide that belongs to the class of 2,6-dinitroaniline compounds. It has a low aqueous solubility and is highly volatile. It acts by inhibiting the mitotic cell divisions in plant root and shoot tips. It is used to protect crops such as cotton, maize, soya beans, peppers, tomatoes, lentils, peanuts, and sunflowers against pre-emergence of a wide spectrum of annual grasses and broad-leaf weeds.
Ethalfluralin is not allowed for use in the European Union and the decision to not include it in Annex I of Directive 91/414/EEC came to force on 12 December 2008. But a maximum residue limit (MRLs) of 0.01 mg/kg has been set according to Reg (EU) No 777/2013 for the presence of ethalfluralin in various products of plant and animal origin.

Application
It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques.
Ethalfluralin CRM can also be used as described below:
Ethalfluralin CRM can also be used as described below:
- Simultaneous determination of seven dinitroaniline herbicide residues using a modified QuEChERS method coupled with gas chromatography-negative chemical ionization–mass spectrometry (GC-NCI/MS) from complex food matrices
- Analysis of 35 multiclass pesticides in honey samples by solid phase extraction and gas chromatography-mass spectrometry
- Development of a multiresidue method for the analysis of 200 pesticides, their degradation products, and 13 polychlorinated biphenyls (PCBs) in water samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS)
- Study the atmospheric degradation of ethalfluralin in order to understand the consequences of ethalfluralin emissions into the atmosphere
- Identification and measurement of 160 pesticides in surface water, stemflow, and throughfall samples, adjacent to agricultural fields by GC-MS
