Dimethyl methylphosphonate is used as a catalyst and a reagent in organic synthesis for the conversion of esters to ketophosphonates. It is an additive for the synthesis of unsaturated polyester resin which has flame retardant high phosphorous and UV-cured epoxy acrylate. It finds application as hydraulic fluids as well.

Clear colorless liquid with a pleasant odor.

Highly flammable. Water soluble. Hydrolyzes slowly upon contact with water.

Dimethyl methylphosphonate is incompatible with strong oxidizing agents and strong bases. Dimethyl methylphosphonate reacts with organic halides at 302-392° F. When heated to temperatures greater than 302° F, Dimethyl methylphosphonate will act as an alkylating agent with basic nitrogen compounds and phenols. Dimethyl methylphosphonate reacts with enol lactones. Dimethyl methylphosphonate has plasticizing properties and may soften or deteriorate some plastics and elastomers (particularly vinyl-based resins, neoprene and natural rubbers) upon contact.
