Used in the synthesis of pyrethroid insecticides, particularly as an intermediate in the production of fenvalerate and related compounds. It contributes to the chiral cyclopropane structure essential for insecticidal activity. The ester group and aryl-substituted cyclopropane ring enable further chemical modifications needed to form the final active ingredient. Commonly employed in agrochemical manufacturing due to its role in building the core scaffold of synthetic pyrethroids, which are valued for their high potency and low mammalian toxicity.
