I. [Product Description]
Mal-PEG-Tosylate is a multifunctional organic intermediate. Its maleimide group can efficiently participate in thiol-specific conjugation reactions, and the tosylate group, as an activation site, is suitable for nucleophilic substitution reactions. The PEG chain imparts excellent water solubility and biocompatibility. This compound is widely used in the fields of polymer synthesis, bioconjugation, and catalyst design, and is a core pharmaceutical intermediate for constructing functionalized materials.
