CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Crystals. Commercially available as oil concentrate and as dust concentrate. Used as an anticoagulant rodenticide. Chronic acting, multiple dose rodenticide. (EPA, 1998) |
|---|---|
| Color/Form | Pale yellow crystals |
| Odor | Odorless |
| Boiling Point | No boiling point at normal pressure; decomposes at 250 °C |
| Melting Point | 284 °F (EPA, 1998) |
| Solubility | In water, 100 mg/L at 20 °C |
| Density | Bulk density = 0.38 g/cu-cm at 20 °C |
| Vapor Pressure | 1X10-4 mPa /7.5X10-10 mm Hg/ at 25 °C |
| LogP | log Kow at 23 °C: 3.08 (pH 4), 2.42 (pH 7), 2.57 (pH 9) |
| Stability/Shelf Life | Very stable and resistant to weathering. |
| Decomposition | When heated to decomposition it emits toxic fumes of hydrogen chloride. |
| Corrosivity | Noncorrosive |
| Surface Tension | 68.9 mN/m at 20.6 °C at 90% saturated solution |
| Dissociation Constants | pKa = 3.40 at 25 °C |
| Other Experimental Properties | pKa = 8.0 (OECD 112 method), but low solubility requires cosolvent that introduces inaccuracy |
| Chemical Classes | Pesticides -> Rodenticides, Anticoagulant |
