Ethyl methacrylate

Ethyl methacrylate is the organic compound with the formula C2H5O2CC(CH3)=CH2.

A colorless liquid, it is a common monomer for the preparation of acrylate polymers.

[1] It is typically polymerized under free-radical conditions.

[3] The related methyl and butyl methacrylates have respective acute LD50s of 10 and 20 g/kg (oral, rat);[1] a linear extrapolation suggests that ethyl methacrylate would have an LD50 of approximately 13 g/kg.

Acrylate esters irritate the eyes and can cause blindness.

E.g. chloroform Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasoline Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazards (white): no code
