Used primarily as a key intermediate in the synthesis of pyrethroid insecticides, this compound plays an important role in the production of agricultural and household pest control agents. Its cyclopropane structure with specific stereochemistry enables effective coupling reactions to form ester linkages typical in synthetic pyrethroids. Due to its chlorinated aromatic group and ester functionality, it contributes to the lipophilicity and biological activity of the final insecticide molecules, enhancing their ability to disrupt insect nervous systems. It is especially valuable in the preparation of analogs with improved stability and potency against resistant insect populations.
