Used as a key intermediate in the synthesis of pyrethroid insecticides, particularly in the production of trans-permethrin and related compounds. Its cyclopropane backbone with specific stereochemistry enables high insecticidal activity by mimicking natural pyrethrum esters. The 3,4-dichlorobenzoyl group enhances lipophilicity and stability, improving pest knockdown and residual effects. Commonly employed in agricultural and household insect control formulations targeting mosquitoes, flies, and other arthropods.
