Dimethyl methylphosphonate

Dimethyl methylphosphonate, or methylphosphonic acid dimethyl ester (DMMP), is a colorless liquid with chemical formula C₃H₉O₃P or CH₃PO(OCH₃)₂. Its melting point is -50 °C and its boiling point is 181 °C. It is combustible. In contact with water it slowly undergoes hydrolysis. May soften some plastics and rubbers. Its CAS number is 756-79-6[1] and its SMILES structure is CP(OC)(OC)=O. Its EINECS number is 212-052-3. Image File history File links Dimethyl_methylphosphonate. ...

The primary commercial use of dimethyl methylphosphonate is as a flame retardant. Other commercial uses are a preignition additive for gasoline, anti-foaming agent, plasticizer, stabilizer, textile conditioner, antistatic agent, and an additive for solvents and low-temperature hydraulic fluids. It can be used as a catalyst and a reagent in organic synthesis, as it can generate a highly reactive ylide. The yearly production in the United States varies between 91,000 and 910,000 kilograms.

Dimethyl methylphosphonate is not classified as toxic, but is harmful if inhaled, swallowed or absorbed through the skin; it is a Chemical Weapons Convention schedule 2 chemical used in the synthesis of Sarin nerve gas. It can also be used as standalone as a simulant for sarin training exercises and for calibration of detectors. It is a suspected carcinogen.
