| | MEPHOSFOLAN Usage And Synthesis |
| Chemical Properties | Mephosfolan is a yellow to amber liquid | | Uses | Insecticide, acaricide. | | General Description | Yellow to amber liquid. Works as an insecticide and acaricide. Not registered as a pesticide in the U.S. | | Reactivity Profile | When heated to decomposition, MEPHOSFOLAN emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. Stable at neutral pH. Hydrolyzed by acid or alkali. [EPA, 1998]. Organophosphates, such as MEPHOSFOLAN, 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 | MEPHOSFOLAN is highly toxic if swallowed or absorbed through the skin. | | Fire Hazard | When heated to decomposition, MEPHOSFOLAN emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. Stable at neutral pH. Hydrolyzed by acid or alkali. | | Safety Profile | Poison by ingestion and
skin contact. When heated to decomposition it emits very toxic fumes of NOx, POx, and
sox. | | Potential Exposure | A potential danger to those involved
in the production, formulation, and application of this
insecticide and acaricide. Not currently registered for use in
the US | | Shipping | N3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1;
Labels: 6.1-Poisonous materials, Technical Name Required | | Incompatibilities | Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Similar organic amides
react with azo and diazo compounds, releasing toxic gases.
Contact with reducing agents can release flammable gases.
Amides are very weak bases but they can react as acids,
forming salts. Mixing amides with dehydrating agents
such as such as phosphorus pentoxide or thionyl chloride
generates the corresponding nitrile. | | Waste Disposal | In accordance with 40CFR
165 recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by following package label directions or by contacting your local or
federal environmental control agency, or by contacting
your regional EPA office |
