Used as a chiral building block in the synthesis of pyrethroid insecticides, which are widely applied in agriculture and household pest control due to their high potency and low mammalian toxicity. Its stereochemistry plays a critical role in the biological activity of the final product, making it essential for producing effective and selective insecticidal agents. Also employed in the preparation of pharmaceuticals and agrochemicals where enantiomeric purity is important for desired biological effects.
