Ethyl chrysanthemumate Usage And Synthesis
Chemical Properties
clear colorless to yellow liquid. Very slightly soluble in water, soluble in alcohol and oils. Powerful, winey-herbaccous, sweet and ethereal, very pleasant odor of intriguing complexity, and with a powerfully lifting minty undertone. The spicy-hcrbaccous, warm and almost green-floral notes resemble certain notes in the Jasmin complex.
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.]
