Chlorfenapyr is an insecticde, and specifically a pro-insecticide (meaning it is metabolized into an active insecticide after entering the host). [1] It is derived from a class of microbially produced compounds known as halogenated pyrroles.

Chlorfenapyr is a member of a new class of chemicals -- the pyrroles. The compound is a pro-insecticide, i.e. the biological activity depends on its activation to another chemical. Oxidative removal of the N-ethoxymethyl group of chlorfenapyr by mixed function oxidases forms the compound CL 303268. CL 303268

Feb 3, 2009 · Chlorfenapyr is a member of the class of pyrroles that is 4-bromo-1H-pyrrole-3-carbonitrile which is substituted at positions 1, 2 and 5 by ethoxymethyl, p-chlorophenyl and trifluoromethyl groups, respectively. A proinsecticide used for termite control and crop protection against several insects and mite pests.

EPA believes the ecological risks and the benefits of this use are both significant, and they are discussed in detail in this summary. This compound clearly helps contain the pest pressures faced by the American cotton producer.

Chlorfenapyr is a completely new insecticide class to combat mosquitoes in public health. It belongs to the pyrrole class of chemistry and has an entirely different mode of action to other insecticides used for vector control. It works by disrupting the insect’s ability to produce energy.

Chlorfenapyr is used as an insecticide-miticide on a number of fruits, vegetables, grains, herbs, spices and tea. At the Forty-third session of CCPR it was scheduled for evaluation by the 2012 JMPR as a

Chlorfenapyr is an arylpyrrole derivative that has high biological activity, ... Creating new insecticide lead compounds based on the design and modification of natural products is a novel process, of which chlorfenapyr is a typical successful example.

Chlorfenapyr EPA registers pesticides under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). In addition, EPA periodically reevaluates pesticides to ensure their safety in light of new scientific and regulatory information.

What is Chlorfenapyr? Chlorfenapyr is a newly developed active ingredient derived from microbes known as pyrroles. Chlorfenapyr has proven to be particularly effective against insects that are resistant to commonly used insecticides. Unlike typical pesticide active ingredients, Chlorfenapyr uniquely activates itself once it enters the host.
