    Chlorfenapyr 122453-73-0


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

    Common name: Chlorfenapyr

    Another name: Alert; Pylon; Citrex; PIRATE; STALKER; Sunfire; Kotersu; Kotetsu; Stealth; Intrepid

    Chemical Name: 4-Bromo-2-(p-chloropenyl)-1-(ethoxymethyl-5- (trifluoromethyl)pyrrle-3-carbonitrile

    Structural formula:

    Empirical formula: C15H11BrClF3N2O
    Mol. Weight: 437.2

    CAS No.: 122453-73-0

    Oral Acute oral LD50 for male rats 441, female rats 1152 mg tech./kg. Skin and eye Acute percutaneous LD50 for rabbits >2000 mg/kg. Moderate eye irritant; non-irritating to skin (rabbits).

Worms NOEC (14 d) for Eisenia foetida 8.4 mg/kg.

    Animals In rats, >60% of orally administered chlorfenapyr was excreted primarily through faeces within 24 hours. The absorbed residues were metabolised via N-dealkylation, dehalogenation, hydroxylation and conjugation. Parent and less polar metabolites were found in egg, milk and tissues such as fat and liver. Metabolism in hens and goats is similar to that in rats, however in these species, 80% of orally administered chlorfenapyr was rapidly excreted. Un-excreted residues were present in kidney and liver. At the potential maximum dietary burden, all residues are <0.01 ppm. Chlorfenapyr is the only significant residue component. Plants In cotton, citrus, tomato, lettuce and potato, chlorfenapyr is dealkylkated to the insecticidally active component (AC 303268) or debrominated to less toxic metabolites. Chlorfenapyr does not translocate out of treated plant parts. Parent compound is the prominent residue. Soil/Environment In soil, chlorfenapyr is the major residue. Debromination to a less toxic metabolite is the primary route; dealkylation is not a primary route of degradation in soil. Koc >10 000 ml/g, indicating chlorfenapyr is likely to be strongly bound in soils. In water DT50 (direct photodegradation) 4.8-7.5 d; stable to hydrolysis at pH 4, 7 and 9.

    Usage: Control of many species of insects and mites, including those resistant to carbamate, organophosphate and pyrethroid insecticides and also chitin-synthesis inhibitors, in cotton, vegetables, c
