| | DIMEFOX Usage And Synthesis |
| Chemical Properties | Colorless liquid; fishy odor; bp 86 °C(186.8 °F) at 15 torr; vapor pressure 0.36 at25 °C (77 °F) (Martin 1974); specific gravity 1.115 at 20 °C (68 °F); oxidized slowly instrong oxidizing agents; decomposes in presence of chlorine; readily soluble in water andin most organic solvents. | | Uses | Insecticide; acaricide. | | Definition | ChEBI: Dimefox is a phosphoramide. | | General Description | Colorless liquid with a fishy odor. Used as an insecticide; is neither produced nor used in the U.S. Not registered as a pesticide in the U.S. | | Reactivity Profile | Highly toxic fumes are given off upon decomposition of DIMEFOX with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. [EPA, 1998]. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. | | Health Hazard | DIMEFOX is extremely toxic; the probable oral lethal dose (human) is 5-50 mg/kg, or 7 drops to 1 teaspoonful for a 150-lb. person. Death may occur from respiratory arrest. Hazards of vapor toxicity are high. | | Health Hazard | Although structural feature in the moleculevaries from most other organophosphoruspesticides, the toxic actions are similarto parathion and other phosphate esters.Extremely toxic by all routes of exposure;cholinesterase inhibitor; can present a serious inhalation hazard, if spilled, due to relatively high vapor pressure; exhibits acute,delayed, and chronic effects; symptoms ofcholinergic effects similar to those of otherorganophosphates; death can result from res-piratory arrest; ingestion of 0.3–2 g could befatal to adult human.
LD50 oral (rat): 1.0 mg/kg. | | Fire Hazard | (Non-Specific -- Insecticide, Liquid, Poisonous, n.o.s.) Highly toxic fumes are given off upon decomposition with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. | | Safety Profile | Poison by ingestion, skin contact,intraperitoneal, subcutaneous, and intravenous routes.When heated to decomposition it emits very toxic fumesof F-, NOx, and POx. |
