Description

Application

Dimethyl methylphosphonate (DMPP) is generally used as a model compound for catalytic degradation studies due to its structural similarity to the organophosphorus compounds used in chemical warfare agents, pesticides and herbicides.[1][2][3]

Used to test SXFA-coated SAW chemical sensors for organophosphorous compound detection
Used as a chemical agent simulant for testing of protective performance of PSS membranes and functionalized sorbent membranes

Reactant for photocatalytic oxidation

Additive for synthesis of:

• Flame retardant high phosphorous containing unsaturated polyester resin
• UV-cured epoxy acrylate / microencapsulated phase change material

Other Notes

Convenient Wittig-Horner reagent[4][5]
