Used as a chain transfer agent in reversible addition-fragmentation chain transfer (RAFT) polymerization, enabling controlled synthesis of well-defined polymers with narrow molecular weight distributions. Its azido-functional group allows for post-polymerization modifications via click chemistry, making it valuable in creating functional polymers for drug delivery systems, surface coatings, and advanced materials. The compound supports the development of block and graft copolymers with precise architectures, useful in nanotechnology and biomedical applications.
