I. [Product Description]
SS-PEG-VA (Disulfide bond-Polyethylene glycol-Valeric acid) is a multifunctional organic intermediate that combines the responsiveness of dynamic reversible disulfide bonds, the hydrophilicity of PEG segments, and the structural modification properties of valeric acid. It is suitable for the functional modification of drug delivery systems and the construction of catalytic reaction systems. As a high-purity pharmaceutical intermediate, it can efficiently participate in the synthesis and functional modification of biocompatible materials.

III. [Application Fields]
    1. Synthesis of responsive nanomaterials (Redox sensitivity of disulfide bonds)
    2. Crosslinking agent in bioconjugation technology (PEG segments enhance solubility)
    3. Construction of functionalized hydrogels (Valeric acid groups provide site modification)
    4. Dynamic linking bridge for targeted carrier systems (Based on the adjustable molecular weight characteristic)
    5. Polymer catalyst loading system (Surface functional modification)
