Used as a reversible addition-fragmentation chain-transfer (RAFT) agent in controlled radical polymerization. Enables precise control over molecular weight and polydispersity of synthesized polymers. Suitable for producing block copolymers, star polymers, and complex architectures in both academic and industrial polymer research. Effective in aqueous and organic media, making it versatile for various monomer types including acrylates, methacrylates, and styrenics. Its stability and efficiency support scalable, reproducible polymer synthesis for coatings, drug delivery systems, and advanced materials.
