I. [Product Description]
OPSS-PEG-PtBA is an amphiphilic block copolymer functionalized with o-pyridyl disulfide/thiol pyridine. It can serve as a high-performance organic intermediate and the core material for drug carrier construction. Its unique reversible disulfide bond and PEG-PtBA block structure endow the product with precise surface modification ability and environmental responsiveness, which is of great value in the construction of catalytic systems and the development of smart materials.

II. [Product Details]
【Appearance】Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
【Stability】Store under refrigeration and avoid repeated freeze-thaw cycles.
【Solvent】Common organic solvents such as chloroform, dichloromethane, and DMSO.
【Molecular Weight】(PEG): 2000, 3400, 5000. Other molecular weights can be customized.
【Storage Conditions】Store in a sealed, dry place at a low temperature below 4°C.
▪ Note: ▶ To ensure product stability, please open the package for use only after constant-temperature drying!

III. [Application Areas]
1. Preparation of responsive nanomaterials (based on the redox sensitivity of disulfide bonds)
2. Construction of polymer self-assembly systems (synergistic effect of the hydrophobic PtBA segment and the hydrophilic PEG segment)
3. Protein/polypeptide bioconjugation reactions (specific thiol coupling of OPSS groups)
4. Development of functional surface coatings (pH-responsive acrylate segments)
5. Basic research on controlled release carriers (dual temperature/reduction responsiveness)
