Descrizione generale
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.
