Butyl methacrylate

Butyl methacrylate is the organic compound with the formula C4H9O2CC(CH3)=CH2. A colorless liquid, it is a common monomer for the preparation of methacrylate polymers.[1] It is typically polymerized under free-radical conditions.[2]

Flammability code 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuelHealth code 1: Exposure would cause irritation but only minor residual injury. E.g. turpentineReactivity code 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorusSpecial hazards (white): no code
