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. | [Synthesis Reference(s)]
