New Pyrethroid Metabolite Standards – Now Available!

Pyrethroid insecticides are synthetic analogs of naturally occurring pyrethrins, which are derived from chrysanthemum flowers. Pyrethroids have been gaining popularity for use against a wide range of insects in place of traditionally used organochlorine (OC) and organophosphorus (OP) pesticides. The increased usage of pyrethroids for agricultural and non-agricultural applications has led to the need for increased testing in environmental and exposure studies, especially in water testing due to known toxicity to fish and other aquatic organisms. The United States Environmental Protection Agency (EPA) is currently reevaluating a total of 23 pyrethroids and pyrethrins for risks to human health and the environment.¹

As with many pesticide analyses, detecting metabolites can be as critical as detecting parent compounds for determination of compound presence after metabolic transformation, and biological activity may be enhanced in the metabolites. At CIL, we are continuing to expand our range of stable isotope-labeled and native pyrethroid standards, recently adding several new standards including 2,3,5,6-tetrafluoro- substituted metabolites, as well as standard solutions of cis-DBCA and cis- and trans-DCCA in MTBE to provide a less reactive polar solvent option.
