I. [Product Description]
Sulfadimethoxine-PEG-p-nitrophenyl carbonate (CAS 1037-50-9) is a ternary complex based on active ester chemical modification, combining the structural characteristics of sulfonamides with the hydrophilic modification ability of PEG segments. As a high-performance organic intermediate, this product can be applied to the bioconjugation reaction system. Its NPC group (p-nitrophenyl carbonate) exhibits excellent amino reaction activity under mild conditions and is suitable for the synthesis of pharmaceutical intermediates and the construction of catalyst carriers.
