I. [Product Description]
cRGD-PEG-Tosyl (Tosylate) is a high-purity organic intermediate. By combining the targeting property of cRGD cyclic peptide with the biocompatibility of PEG chain, it realizes molecular directional coupling. Its tosylate group can serve as an efficient leaving group, which is widely used in bioconjugation reactions and functional modification of polymer materials. This product is of great value in the construction of nano-carriers and the development of biological probes, and is suitable for the synthesis of pharmaceutical intermediates and the optimization of catalytic systems.
