I. [Product Description]
OPSS-PEG-Sodium Alginate is a functionalized polymer compound composed of o-pyridyldithio (OPSS) groups, polyethylene glycol (PEG) segments, and sodium alginate, which combines biocompatibility and controllable reaction activity. As an organic intermediate and pharmaceutical intermediate, its OPSS groups can efficiently achieve thiol-directed coupling, the PEG segments enhance water solubility, and the sodium alginate provides a three-dimensional network structure. It has important application value in the fields of catalytic reaction system construction and biomaterial engineering.

III. [Application Fields]
1. Surface modification of functionalized nanoparticles (through OPSS-SH bond-directed immobilization of targeting molecules)
2. Construction of controllable coupling systems for proteins/antibodies
3. Cross-linking agents for biodegradable hydrogels (utilizing the calcium-ion response characteristics of sodium alginate)
4. Hydrophilic modification of polymer materials (regulation of steric hindrance by PEG segments)
5. Design of catalytic reaction carriers (chelation of metal ions and exposure of active sites)
