cyfluthrin cyfluthrin cyfluthrin is a pyrethroid insecticide and common household pesticide. it is a complex organic compound and the commercial product is sold as a mixture of isomers. like most pyrethroids (moa 3a), it is highly toxic to fish and invertebrates, but it is far less toxic to humans. it is generally supplied as a 10–25% liquid concentrate for commercial use and is diluted prior to spraying onto agricultural crops and outbuildings. cyfluthrin names preferred iupac name (r)-cyano(4-fluoro-3-phenoxyphenyl)methyl (1r,3r)-3-(2,2-dichloroethen-1-yl)-2,2-dimethylcyclopropane-1-carboxylate identifiers cas number 68359-37-5 y 3d model (jsmol) interactive image chembl chembl2104608 n chemspider 45482 y echa infocard 100.063.485 kegg c10982 y pubchem cid 50153 unii scm2qlz6s0 y comptox dashboard (epa) dtxsid5035957 inchi inchi=1s/c22h18cl2fno3/c1-22(2)15(11-19(23)24)20(22)21(27)29-18(12-26)13-8-9-16(25)17(10-13)28-14-6-4-3-5-7-14/h3-11,15,18,20h,1-2h3/t15-,18-,20-/m0/s1 ykey: qqodlkzgrkwifg-qsfxbcczsa-n yinchi=1/c22h18cl2fno3/c1-22(2)15(11-19(23)24)20(22)21(27)29-18(12-26)13-8-9-16(25)17(10-13)28-14-6-4-3-5-7-14/h3-11,15,18,20h,1-2h3/t15-,18-,20-/m0/s1key: qqodlkzgrkwifg-qsfxbcczbf smiles cl/c(cl)=c/3(c(=o)o(c#n)c2ccc(f)c(oc1ccccc1)c2)c3(c)c properties chemical formula c22h18cl2fno3 molar mass 434.29 g·mol−1 melting point 60 °c (140 °f; 333 k) solubility in water 2 μg/l pharmacology atc code p03ba01 (who) qp53ac12 (who) except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references safety in rats, the ld50s are 500, 800 (oral), and 600 (skin) mg/kg. excessive exposure can cause nausea, headache, muscle weakness, salivation, shortness of breath and seizures. in humans, it is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, whose urinary excretion half-lives are in a range of 5–7 hours. worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantification of cyfluthrin in blood or plasma. health and safety risks are controlled by right to know laws that exist in most developed countries. cyfluthrin is regulated in the us by the epa.
