Used in polymer chemistry as a reversible addition-fragmentation chain transfer (RAFT) agent, it helps control the polymerization process to produce polymers with specific molecular weights and narrow distributions. This chemical is particularly valuable in creating block copolymers and functionalized polymers, which are essential in advanced materials like coatings, adhesives, and drug delivery systems. Its role in RAFT polymerization enables precise design of polymer structures, enhancing material properties for industrial and biomedical applications.
