General description
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.

Tralomethrin is a synthetic Type II pyrethroid insecticide that contains an a-cyano group and shows more neurotoxicity than Type I insecticides. It acts by modifying the kinetics of the voltage-gated sodium channels present in the axonal membranes of neurons. In addition, the voltage-gated calcium and chloride channels and GABA (gamma amino butyric acid) receptors are the secondary target sites for tralomethrin.
Tralomethrin is not approved for use in the European Union (EU) as per the Commission Regulation (EC) No 2076/2002 of 20th November 2002 as a plant protection agent under Regulation (EC) No. 1107/2009, repealing the directive 91/414/EEC. But a default maximum residue limit (MRL) of 0.01 mg/kg is applicable for its presence in products of plant origin according to Art 18(1)(b) Reg 396 / 2005.
