Fenazaquin is an insecticide/acaricide that belongs to the class of quinazoline compounds. It shows ovicidal activity against phytophagus mites found in agricultural crops of almonds, citrus fruits, and grapes. It is highly lipophilic and inhibits site I of the electron transport chain in mitochondria. Its acceptable daily intake (ADI) according to body weight is 0.005 mg/kg.
Fenazaquin was approved for use in the European Union on 1^st June 2011 following a request for its inclusion according to Reg. 33/2008 and its approval for use expires on 31st May 2023. The maximum residue limit (MRL) for fenazaquin in citrus fruits is 0.5 mg/kg and 0.2 mg/kg in tree nuts. Fenazaquin 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.
It may also find following uses:

• Determination of trace levels of fenazaquin in raw almond samples using dispersive magnetic solid phase extraction (DMSPE) and gas chromatography-mass spectrometry (GC-MS)
• Development of a liquid phase microextraction method using eutectic solvents for extraction from different fruit and vegetable samples and gas chromatography determination
• Switchable solvent microextraction of pesticide residues from food and environmental samples
• Evaluation of 60 pesticide residues in 144 different fruit and vegetable samples by LC-MS/MS method
• Study of matrix effects in pesticide residue analysis in different citrus fruits using ethyl acetate for extraction and Ultrahigh-Performance Liquid Chromatography–High-Resolution Mass Spectrometry for determination
• Residue analysis of 64 pesticides from various groups by nanoflow liquid chromatography-mass spectrometry (LC-MS)
