General description

2,2′-Azobis(2-methylbutyronitrile), also known as AIBN, is a free radical initiator that is widely used in organic synthesis for a variety of reactions. It is often used as an initiator in the synthesis of various polymers, such as polystyrene, polyacrylamide, and poly(methyl methacrylate).

Application

2,2′-Azobis(2-methylbutyronitrile) can be used as a radical initiator in the synthesis of bibenzo[b][1,4]thiazine derivatives by a free-radical condensation reaction 2,2′-dithiodianiline and methyl aryl ketones. It is also used in the synthesis of polyacrylonitrile nanoparticles via semi-continuous emulsion polymerization.
