CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Resmethrin appears as colorless crystals or waxy solid. Insoluble in water. Used as an insecticide. |
|---|---|
| Color/Form | Waxy off-white to tan solid |
| Odor | Chrysanthemate odor |
| Boiling Point | Decomposes at >180 °C |
| Melting Point | 56.5 °C (pure (1-RS)-trans isomer) |
| Solubility | Very sol in xylene and aromatic petroleum hydrocarbons; solubility in kerosene 10% |
