I. [Product Description]
NPC-PEG-CHO is a multifunctional organic intermediate that combines the high reactivity of nitrophenyl carbonate (NPC) with the specific coupling ability of aldehyde group (CHO). It is suitable for biological coupling, polymer material synthesis, and catalyst carrier preparation. Its polyethylene glycol (PEG) chain can adjust the hydrophilicity and steric hindrance, significantly improving the solubility and stability of the product. It is widely used in the development of pharmaceutical intermediates and the modification of functional materials.
