I. [Product Description]
Tosyl-PEG-Ornithine is a multifunctional organic intermediate. Through the synergistic effect of the toluenesulfonyl activating group and the polyethylene glycol (PEG) chain, it significantly improves the efficiency of bioconjugation reactions. As a pharmaceutical intermediate, its unique ornithine structure can precisely regulate the surface charge of molecules, making it suitable for the construction of catalytic systems and the development of functional materials.
