This chemical is primarily used in the field of polymer science and materials engineering. It serves as a versatile crosslinking agent and initiator in controlled radical polymerization processes, particularly in atom transfer radical polymerization (ATRP). Its application is crucial in the synthesis of well-defined polymers with controlled molecular weights and architectures, such as block copolymers, star polymers, and graft polymers. Additionally, it is employed in surface modification techniques to create functionalized surfaces with specific properties, such as improved adhesion, biocompatibility, or responsiveness to external stimuli. Its disulfide bond allows for the incorporation of dynamic and reversible properties in materials, making it valuable in the development of self-healing polymers and drug delivery systems.
