I. [Product Description]
Collagen-PEG-Tosy is a tosylate-activated collagen-polyethylene glycol conjugate. As a high-performance organic intermediate and pharmaceutical intermediate, its unique active groups can efficiently participate in bioconjugation reactions. This compound combines the biocompatibility of collagen with the steric hindrance effect of PEG, which can significantly improve the stability of the product in the catalytic reaction system and is suitable for constructing complex functionalized material systems.
