一般說明

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.

Chlorfluazuron belongs to the family of benzoylurea insecticides used against various crops, fruits, and vegetables. It is a chitin synthesis inhibitor and controls the lepidopteran pests by disrupting molting and subsequent completion of their life cycle due to incomplete exoskeleton formation.
As per the commission regulation no 1107/2009, repealing the council directive 91/414/EEC, chlorfluazuron is not approved for use in the European Union. But according to Art 18(b) Reg 396/2005, a default maximum residue limit (MRL) of 0.01 mg/kg is applicable, wherever necessary.

應用

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

  • To study the metabolism of chlorfluazuron and flonicamid in tea samples using a modified QuEChERS extraction and UPLC-MS/MS quantification
  • Determination of chlorfluazuron residues in Chinese cabbage, Chinese kale, Chinese lettuce, and cauliflower by ultra high-performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS)
  • Development and validation of a gas chromatography-mass spectrometry (GC-MS) method for the detection and measurement of chlorfluazuron in termites
  • To determine 9 benzoylurea insecticides in samples of whole milk, rice, egg, lemon, lettuce, beef meat, and avocado using pressurized liquid extraction and liquid chromatography-mass spectrometry(LC-MS)
  • To develop a method based on in-syringe dispersive liquid-liquid microextraction and HPLC determination for the analysis of 5 benzoylurea insecticides in water and tea beverage samples
  • Analysis of benzoylurea insecticides in tea samples using Fe3O4- hyperbranched polyester (HBPE) nanocomposite as an adsorbent for magnetic solid phase extraction (MSPE) and HPLC

A novel in-syringe dispersive liquid-liquid microextraction based on the solidification of ionic liquids (in-syringe SIL-DLLME) was coupled with high-performance liquid chromatography-ultraviolet detector (HPLC-UVD) to detect five benzoylurea insecticides (BUs) in water and tea beverage samples. In this method, the hydrophobic
