  • Applications

    2,2'-Azobis(2-methylbutyronitrile) (CAS 13472-08-7) is an azo-type free-radical initiator that decomposes upon heating to generate radicals and initiate polymerization. In industrial settings, it is commonly used to initiate radical polymerizations of vinyl and acrylate monomers for coatings and paints, inks, adhesives, and plastics; it is also employed in polymer synthesis and crosslinking systems in industrial manufacturing and in laboratory polymerization studies.
