Used primarily as a reversible addition-fragmentation chain transfer (RAFT) agent in polymer chemistry, it facilitates controlled radical polymerization. This allows for the synthesis of polymers with precise molecular weights and narrow polydispersity, essential for creating advanced materials with specific properties. It is particularly valuable in producing block copolymers, which are used in nanotechnology, drug delivery systems, and coatings. Its application also extends to surface modification and functionalization of materials, enhancing their performance in various industrial and biomedical applications.
