I. [Product Description]
Collagen-PEG-SPDP is a multifunctional organic intermediate that covalently bridges collagen and dithiopyridine disulfide (SPDP) through polyethylene glycol (PEG), combining excellent biocompatibility and controllable cross-linking properties. As an efficient pharmaceutical intermediate, this compound is widely used in bioconjugation reactions and the construction of catalytic systems. Its reversible disulfide bond design supports dynamic molecular modification and directional functionalization.
