I. [Product Description]
NPC-PEG-VS Nitrophenyl carbonate-polyethylene glycol-vinyl sulfone is a multifunctional organic intermediate with potential applications in both pharmaceutical intermediates and polymer material modification. The vinyl sulfone group (VS) in its structure can efficiently react specifically with sulfhydryl groups, while the PEG segment provides excellent hydrophilicity and adjustable molecular weight. It is suitable for fields such as bioconjugation, material surface functionalization, and catalytic system construction.
