Used as a key chiral building block in the synthesis of active pharmaceutical ingredients, particularly in the production of pyrethroid insecticides and certain antiviral agents. Its rigid cyclopropane structure and defined stereochemistry make it valuable for introducing conformational restraint in drug design, enhancing selectivity and metabolic stability. Commonly employed in asymmetric synthesis to control stereochemical outcomes. Also utilized in the preparation of specialty agrochemicals where chirality impacts biological activity.
