Dimethyl methylphosphonate Usage And Synthesis

Chemical Properties

colourless liquid

Uses

NMR probe for cell volume. Flame retardant. Simulant for nerve agents.

Uses

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

Synthesis Reference(s)

Synthetic Communications, 20, p. 239, 1990 DOI: 10.1080/00397919008052289

General Description

Clear colorless liquid with a pleasant odor.

Air & Water Reactions

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

Reactivity Profile

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.

Health Hazard

Dimethyl methylphosphonate (DMMP) administered to male rats is a reproductive toxicant and carcinogen. Effects in humans are unknown.

Fire Hazard

Dimethyl methylphosphonate is combustible.

Safety Profile

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
