I. [Product Description]
SS-PEG-PBA is a multifunctional organic intermediate based on dynamic cross-linking of disulfide bonds, hydrophilic modification of polyethylene glycol segments, and phenylboronic acid functionalization. Its core value lies in achieving intelligent responsive dissociation through reversible disulfide bonds, combining the biocompatibility of PEG and the targeted recognition characteristics of PBA. It is suitable for fields such as the construction of catalytic systems, the development of nanocarriers, and the synthesis of functional materials.
