I. [Product Description]
Sulfo NHS-PEG-SS-PEG-NHS is a bifunctional symmetric organic intermediate with both high-efficiency cross-linking ability and controllable degradation characteristics. The disulfide bond (SS) in its molecule can achieve reductive-responsive cleavage, and the PEG chain provides excellent water solubility and biocompatibility. It is widely used in the preparation of pharmaceutical intermediates and the synthesis of polymer materials, especially suitable for the construction of catalytic systems that require precise controlled release.
