I. [Product Description]
NPC-PEG-SH (nitrophenyl carbonate-polyethylene glycol-thiol) is a multifunctional organic intermediate with both high-efficiency coupling characteristics and controllable reaction activity. It is widely used in the preparation of pharmaceutical intermediates and the modification of polymer materials. Its unique PEG backbone and dual-functional group design of thiol/nitrophenyl carbonate can precisely regulate the intermolecular interactions, suitable for the synthesis of biocompatible materials and the functional modification of catalyst carriers.
