Used primarily as an intermediate in the synthesis of pyrethroid insecticides, ethyl chrysanthemate plays a key role in the production of synthetic analogs of natural pyrethrins. These insecticides are widely applied in agriculture, household pest control, and public health programs due to their high efficacy against a broad spectrum of insects and relatively low toxicity to mammals. The compound contributes to the structural backbone of pyrethroids, enhancing their stability and biological activity. It is also utilized in research and development for new agrochemicals and in the formulation of environmentally friendly pest control agents.
