Dinoseb is a selective nitrophenolic herbicide used for protection against postemergence of grass and broad-leaf weeds in vegetables, fruits, nuts, and other field crops such as soybeans. In addition, it also finds its use as an insecticide for grapes, and as a seed drying agent. It acts by uncoupling oxidative phosphorylation in mitochondria and inhibiting ATP synthesis.
Under the Regulation (EC) No 1107/2009 and withdrawing the Council Directives 79/117/EEC and 91/414/EEC, dinoseb is not approved for its use as a plant protection product in the European Union (EU). It was also banned for use as a pesticide in the US in 1986 by the US EPA (Environmental Protection Agency). But a default maximum residue limit (MRL) in the range of 0.02 mg/kg to 0.1 mg/kg is set for the presence of dinoseb (measured as a sum of dinoseb, its salts, dinoseb-acetate, and binapacryl) in products of plant and animal origin.

Application

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

• Simultaneously determine dinoseb and pendimethalin in surface water samples using optimized direct injection (DI) and solid phase extraction (SPE) coupled to ultra high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS)
• Evaluate anodic voltametric analysis of dinoseb in river water samples using a boron doped diamond electrode following cathode pre-treatment and in the presence of cationic surfactants
• Extract 15 phenols from refinery wastewater samples by dispersive liquid-liquid microextraction (DLLME) technique and identify them by liquid chromatography-photodiode array detector (LC-PDA)
• Detect chlorophenoxy acid methyl esters and other chlorinated herbicides in peppermint tea, plum, and orange peel extract soft ionization gas chromatography coupled to quadrupole time-of-flight mass spectrometry (GC-QTOFMS)
• Analyze 32 pesticide residues of four different chemical classes in tea brew and tea leaves samples by a sample treatment method based on metabolomics and liquid chromatography-mass spectrometry (LC-MS)
• Determine pendimethalin, dinoseb and sodium 5-nitroguaiacolate in vegetable samples by differential pulse voltammetry (DPV) and chemometrics
