I. [Product Description]
WSW(WSWGPYS)-PEG-Tosyl(Tosylate) is a multifunctional organic intermediate. It is synthesized by coupling a precisely designed liver-targeting polypeptide sequence with polyethylene glycol (PEG) and modifying the terminal with a tosylate group, which significantly enhances its water solubility and biocompatibility. This compound exhibits excellent stability in catalytic reaction systems and can be used as a pharmaceutical intermediate for the construction and functional modification of targeting molecules.
