Used primarily as a polymerization initiator in the synthesis of acrylic polymers and resins. It enables controlled radical polymerization, making it valuable in producing adhesives, coatings, and specialty plastics. Also serves as an intermediate in organic synthesis, particularly in pharmaceuticals and fine chemicals, due to its ability to introduce carboxylic acid and nitrile functional groups in chain-extended molecules. Its stability and reactivity profile make it suitable for use in emulsion and solution polymerization processes.
