CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Allethrin appears as a clear amber-colored viscous liquid. Insoluble and denser than water. Toxic by ingestion, inhalation, and skin absorption. A synthetic household insecticide that kills flies, mosquitoes, garden insects, etc. |
|---|---|
| Boiling Point | BP: 140 °C at 0.1 mm Hg. Vaporizes without decomposition when heated at 150 °C. |
| Melting Point | ~4 °C |
| Flash Point | GREATER THAN 140 °F |
| Solubility | Solubility in water: none |
| Density | Relative density (water = 1): 1.01 |
| Vapor Pressure | Pale, yellow, oily liquid. Specific gravity, d 20/4: 1.005-1.015. Vapor pressure: 1.2X10-4 mm Hg at 30 °C. Miscible with most organic solvents at 20-25 °C. /Pynamin forte/ |
| LogP | 4.78 |
| Stability/Shelf Life | MORE STABLE TOWARDS UV LIGHT THAN NATURAL PYRETHRINS |
| Decomposition | When heated to decomposition it emits acrid fumes. |
| Refractive Index | Oily pale yellow liquid. Index of refraction: 1.5156 at 20.6 °C/D. UV max (ethanol): 232 nm (epsilon 23000). Practically insoluble in water. /Allethrin II/ |
| Kovats Retention Index | 2063 2034 2053 2060.7 2048.1 |
| Other Experimental Properties | Allethrins are sometimes classified as type I pyrethroids, since they lack an alpha-cyano substituent. |
| Chemical Classes | Pesticides -> Pyrethrins/Pyrethroids |
