I. [Product Description]
Tosylate-PEG-PEI is a multifunctional organic intermediate. Through the synergistic effect of the high reactivity of the tosylate group and the cationic properties of PEI, it is suitable for the synthesis and functional modification of polymer materials. Its PEG segment can regulate the hydrophilic-hydrophobic balance. It has excellent biocompatibility and stability in the field of pharmaceutical intermediates. At the same time, it can be used as an efficient catalyst carrier to improve the controllability and reproducibility of the reaction system.
