1. [Product Description]
    SPDP-PEG-NHS3-(2-Pyridyldithio)propionic acid N-hydroxysuccinimide ester-polyethylene glycol-N-hydroxysuccinimide ester is a multifunctional organic intermediate with both high-efficiency cross-linking ability and controllable reaction activity. Through the dynamic reversible property of the pyridine disulfide bond and the high-efficiency coupling effect of the NHS ester, this compound is widely used in the fields of bioconjugation and material surface modification. The PEG segment endows the product with excellent water solubility and biocompatibility, making it an ideal catalyst carrier for constructing functional molecular systems.
