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] In terms of the acute toxicity of butyl methacrylate, the LD50 is 20 g/kg (oral, rat).

It is an irritant to the eyes and can cause blindness.

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 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 fuel 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
