I. [Product Description]
OPSS-PEG-DTPA is a multifunctional organic intermediate that integrates the dynamic covalent bond characteristics of ortho-pyridyl disulfide (OPSS), the biocompatibility of polyethylene glycol (PEG), and the strong chelating ability of diethylenetriaminepentaacetic acid (DTPA). This compound has high application value in bioconjugation, metal ion loading, and catalytic systems, and can serve as the core module for pharmaceutical intermediates or functional material design.

II. [Product Details]
【Appearance】Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
【Stability】Store 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.

▪ Precautions: ▶ To ensure product stability, please open the package for use only after constant-temperature drying!

III. [Application Areas]
1. Surface functional modification of nanomaterials (based on the directional coupling of OPSS)
2. Metal ion chelating carrier (efficient loading of rare-earth/transition metals by DTPA)
3. Site-specific labeling of proteins/antibodies (through the thiol-disulfide exchange reaction)
4. Construction of biosensor probes (PEG enhances water solubility and stability)
5. Cross-linking agent for polymer materials (controllable dynamic bonding system)
