I. [Product Description]
SS-PEG-NPC (Disulfide-Polyethylene Glycol-Nitrophenyl Carbonate) is a multifunctional organic intermediate. By combining the dynamic reversible property of the disulfide bond (SS) with the biocompatibility of polyethylene glycol (PEG), it significantly enhances the stability and responsiveness of the carrier. This compound can be used as an efficient pharmaceutical intermediate for constructing stimulus-responsive drug delivery systems. Meanwhile, its nitrophenyl carbonate group (NPC) can serve as an active site to achieve precise coupling reactions with the assistance of a catalyst.
