Used primarily in the synthesis of pyrethroid insecticides, methyl chrysanthemate serves as a key intermediate in creating compounds with high insecticidal activity. These synthetic pyrethroids are widely applied in agriculture, household pest control, and public health programs to manage mosquitoes, flies, and other insect pests. Due to its structural role, it contributes to the stability and effectiveness of the final insecticide molecules. Its derivatives are favored for their rapid knockdown effect on insects and relatively low toxicity to mammals, making them suitable for use in residential and agricultural settings.
