prallethrin

Uses: It is high vapor pressure. It is used for prevention and control of mosquito, fly and roach etc. In knok down and killing active, it is 4 times highter than d-allethrin. Especially it has the function to wipe out roach. It's therefore used as active ingredient mosquito-repellent insect. Electro-thermal, mosquito repellent incense, Aerosol and spraying products. The used amountin mosquito-repellent incense is 1/3 of that d-allethrin,Generally the used amount in aerosol is 0.25%.Chemical Name:(S)-2-methyl-3-(2-propynyl)-4-oxocyclopent-2-enyl-(1R)cis-trans-2,2-dimethyl-3-(2-methyl- 1-propenyl)cyclopropanecarboxylate Formula:c19h24O3 Formula Weight:300.40 CAS NO:23031-36-9Appearance:pale yellow to brown viscous liquid.
