Sethoxydim is a selective, systemic, and cyclohexanedione oxime herbicide, absorbed mainly by foliage, and, to a lesser extent, by roots. It is an acetyl CoA carboxylase (ACCase) inhibitor, which inhibits the incorporation of acetate into fatty acids and interferes with the formation of phospholipids used in building new membranes. It is used to control annual and perennial grass weeds (except Poa spp.) in broad-leaved crops, including cotton, oilseed rape, soybeans, sugar beets, fodder beets, sunflowers, spinach, potatoes, tobacco, peanuts, strawberries, alfalfa, flax, and vegetables.
Sethoxydim is not approved for use in the European Union (EU) as a plant protection agent, following Regulation (EC) No. 1107/2009 and repealing Directive 91/414/EEC. But maximum residue levels of 0.05 mg/kg to 10 mg/kg are allowed for the presence of sethoxydim, expressed as a sum of sethoxydim and clethodim including their degradation products, in products of plant and animal origin, according to the EU Reg. No 839/2008.

應用

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Sethoxydim CRM may also be used as given below:

• Simultaneous residue analysis of 379 pesticides in human serum samples using the QuEChERS extraction method and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Method development for multi-residue analysis of pesticides in agricultural water samples, extracted by QuEChERS method using liquid chromatography (LC) with mass spectrometry (MS)
• Determination of 260 pesticide residues in human urine samples using a scaled-down QuEChERS approach for sample extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Evaluation of liquid chromatography high-resolution mass spectrometry (UHPLC-HRMS) using time-of-flight mass spectrometry as an accurate-mass multi-residue screening method to estimate multi-class organic contaminants in baby food samples
• Development of a semi-automated method for the analysis of 261 pesticides and 41 environmental contaminants in catfish muscle samples by QuEChERS sample extraction and low pressure-GC-MS/MS and UHPLC-MS/MS, following an automated robotic micro-SPE clean-up
• Multi-residue analysis of 200 pesticides and 65 environmental contaminants in 10 samples of cattle, swine, and chicken muscles by fast low-pressure gas chromatography (LP-GC-MS/MS) and ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
