Used as a chain transfer agent in radical polymerization processes, enabling control over molecular weight and polydispersity of synthesized polymers. Its trithiocarbonate group facilitates reversible addition-fragmentation chain transfer (RAFT), making it valuable in producing well-defined copolymers with specific architectures. Commonly applied in the development of functional polymers for coatings, adhesives, and biomedical materials. Also employed in surface modification and polymer conjugation due to reactive carboxyl groups that allow further chemical derivatization.
