I. [Product Description]
NPC-PEG-TK-NPC is a multifunctional organic intermediate. The synergistic effect between the nitrophenyl carbonate (NPC) group and the ketal thiol (TK) bond in its structure endows the product with excellent acid-base responsiveness and controllable degradation characteristics. As a key module for the synthesis of high-efficiency pharmaceutical intermediates and polymer materials, this compound demonstrates unique value in the construction of stimulus-responsive carriers and catalytic coupling reactions.
