As a flame retardant, a preignition
additive for gasoline, an antifoam agent, a plasticizer
and stabilizer, a textile conditioner, and
an antistatic agent; used experimentally to
mimic the physical and spectroscopic (but not
biological) properties of anticholinesterase
agents
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.
NMR probe for cell volume. Flame retardant. Simulant for nerve agents.
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.
Dimethyl methylphosphonate
(DMMP) administered to male rats is a reproductive
toxicant and carcinogen. Effects in
humans are unknown.
Dimethyl methylphosphonate is combustible.
Moderately toxic by
intravenous route. Experimental
reproductive effects. Questionable
carcinogen with experimental carcinogenic
data. Mutation data reported. An
experimental nerve gas stimulant. A flame
retardant. When heated to decomposition it
emits toxic fumes of POx
The ITSL for dimethyl methyl phosphonate is 700 μg/m3 based on an annual averaging time.
