Ethyl chrysanthemumate Usage And Synthesis

Chemical Properties

clear colorless to yellow liquid

Uses

Ethyl Chrysanthemate is an organic building block used in the synthesis of various chemical compounds, such as insecticide, Resmethrin (R144685). It is used in the preparation of trans-norchrysanthemates and trans-norpyrethrates, having insecticidal activity.

Purification Methods

Purify the ester by vacuum distillation. The free trans-acid has m 54o (from EtOAc), and the free cis-acid has m 113-116o (from EtOAc). The 4-nitrophenyl ester has m 44-45o (from pet ether) [Campbell & Harper J Chem Soc 283 1945, IR: Allen et al. J Org Chem 22 1291 1957]. [Beilstein 9 II 45.]
