Used primarily as an intermediate in the synthesis of pyrethroid insecticides, ethyl chrysanthemate plays a key role in agrochemical manufacturing. It contributes to the formation of ester structures found in synthetic pyrethroids, which are widely used for their high insecticidal activity and low mammalian toxicity. These insecticides are effective against a broad spectrum of pests in agriculture, public health, and household products. Due to its reactivity and structural properties, ethyl chrysanthemate is valued in the production of environmentally favorable pest control agents that mimic natural pyrethrins.
