Cypermethric acid synthesis

Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate it… Web55701-03-6 1R-trans-Permethrinic Acid (1R,3S)-3- (2,2-Dichloroethenyl)-2,2-dimethyl-cyclopropanecarboxylic Acid; (1R-trans)-3- (2,2-Dichloroethenyl)-2,2-dimethyl-cyclopropanecarboxylic Acid; (1R)- (+)-trans-Permethrinic Acid; 1R-trans-Permethric Acid; 1R-trans-Permethrinic Acid C₈H₁₀Cl₂O₂ TRC Product Detail
