I. [Product Description]
SH-PEG-SPDP is a multifunctional organic intermediate. Its structure integrates a sulfhydryl group, a polyethylene glycol (PEG) chain, and an SPDP active group, and it has precise site selectivity in bioconjugation reactions. As an efficient pharmaceutical intermediate, it can achieve controlled release through the dynamic cross-linking property of disulfide bonds. Meanwhile, the PEG chain imparts excellent water solubility and biocompatibility. This compound can directionally construct a molecular bridging system under mild conditions in the presence of a catalyst.
