I. [Product Description]
Tosyl-PEG-bromide is a multifunctional organic intermediate that combines the high reactivity of tosyl groups with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). It is widely used for the functional modification of biomolecules and the synthesis of polymer materials. The bromide end can efficiently participate in nucleophilic substitution reactions and serves as a core catalyst carrier for constructing complex molecular structures.
