I. [Product Description]
    SS-PEG-DTPA is a multifunctional organic intermediate. Its core structure bridges polyethylene glycol (PEG) and diethylenetriaminepentaacetic acid (DTPA) through a dynamic disulfide bond, combining biocompatibility, adjustable molecular weight, and metal chelating ability. This compound can be used as a pharmaceutical intermediate to construct responsive nanocarriers or play a molecular bridging role in catalytic systems, significantly enhancing the functional design space of materials.

II. [Product Details]
    【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
    【Stability】 Store refrigerated and avoid repeated freezing and thawing.
    【Solvents】 Conventional 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 low-temperature, sealed, and dry environment below 4°C.
▪ Precautions: ▶ To ensure product stability, please open the package for use after constant-temperature drying!

III. [Application Areas]
    1. Crosslinking agent for responsive drug delivery systems (due to the reductive cleavage property of the disulfide bond).
    2. Surface modification of functionalized nanoparticles (the PEG segment enhances dispersibility).
    3. Construction of metal ion chelating carriers (due to the chelating group of DTPA).
    4. Functional graft modification of polymer materials.
    5. Spacer arm design in bioconjugation reactions.
