Safety Information
MEPHOSFOLAN Usage And Synthesis
  • Chemical PropertiesMephosfolan is a yellow to amber liquid
  • UsesInsecticide, acaricide.
  • General DescriptionYellow to amber liquid. Works as an insecticide and acaricide. Not registered as a pesticide in the U.S.
  • Reactivity ProfileWhen 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 HazardMEPHOSFOLAN is highly toxic if swallowed or absorbed through the skin.
  • Fire HazardWhen 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 ProfilePoison by ingestion and skin contact. When heated to decomposition it emits very toxic fumes of NOx, POx, and sox.
  • Potential ExposureA potential danger to those involved in the production, formulation, and application of this insecticide and acaricide. Not currently registered for use in the US
  • ShippingN3018 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
  • IncompatibilitiesIncompatible 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 DisposalIn 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
