I. [Product Description]
OPSS-PEG-Chloride is a multifunctional organic intermediate with the characteristics of both an efficient catalyst and a bioconjugation crosslinker. Its ortho-pyridyl disulfide bond (OPSS) reacts specifically with thiol groups. Combining the hydrophilicity and adjustable molecular weight of the PEG chain, it is widely used in the synthesis of pharmaceutical intermediates and the preparation of functional materials, and supports molecular weight customization from 2000-5000 Da.

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.
【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 in a sealed, dry place at a low temperature below 4°C.
▪ Notes: ▶ To ensure product stability, please open the package for use only after constant-temperature drying!

III. [Application Fields]
1. Site-specific conjugation and labeling of biomacromolecules (such as antibodies and polypeptides).
2. Surface functional modification of nanomaterials (gold nanoparticles, quantum dots).
3. Construction of polymer cross-linked networks.
4. Interface modification of microfluidic chip biosensors.
5. Design of controlled drug delivery system carriers.
