I. [Product description]
SS-PEG-serine (Disulfide bond-Polyethylene glycol-Serine) is a multifunctional organic intermediate. Its unique disulfide bond structure endows it with reversible cross-linking properties, which is of great value in the assembly of nanomaterials and the modification of polymers. As a pharmaceutical intermediate, this compound enhances water solubility through the PEG segment, and the serine end-group provides active modification sites, which is suitable for the construction of catalytic carriers and the precise synthesis of biocompatible materials.
