I. [Product Description]
OPSS-PEG-PBA is a multifunctional organic intermediate that combines the dynamic covalent bond characteristics of ortho-pyridyl disulfide (OPSS), the biocompatibility of polyethylene glycol (PEG), and the targeted binding ability of phenylboronic acid (PBA). It is widely used in bioconjugation, polymer material modification, and the construction of catalytic reaction systems. This compound can serve as a pharmaceutical intermediate or a catalyst carrier and has important research value in the fields of controlled release and targeted delivery.

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

III. [Application Fields]
    1. Preparation of coupling ligands for targeted drug delivery systems (based on the specific binding of PBA to cis-diols).
    2. Surface functionalization of biosensors (utilizing the rapid exchange reaction between OPSS and thiols).
    3. Development of intelligent polymer materials (PEG segments regulate the hydrophilic-lipophilic balance).
    4. Targeted modification of nanoparticles (enhancing selective cellular endocytosis).
    5. Construction of enzyme immobilization carriers (directional coupling mediated by phenylboronic acid).
