I. [Product Description]
SPDP-PEG-OH3-(2-Pyridyldithio)propionic acid N-hydroxysuccinimide ester-polyethylene glycol-hydroxy is a multifunctional organic intermediate with both high-efficiency coupling activity and controlled-release characteristics. Its core value lies in the realization of dynamic cross-linking through the pyridyldithio bond, combined with the excellent water solubility and biocompatibility of the PEG segment, and it is widely used in bioconjugation reactions, polymer material synthesis, and nano-carrier construction. This compound can be used as a pharmaceutical intermediate or catalyst, showing precise site selectivity in the assembly of complex molecules.
