I. [Product Introduction] 
PVC2000-PEG-NHS is an amphiphilic block copolymer that combines the mechanical stability of polyvinyl chloride (PVC) with the biocompatibility of polyethylene glycol (PEG). The N-hydroxysuccinimide ester (NHS) group at its end can efficiently react specifically with amino groups. As a high-performance organic intermediate, it is widely used in the fields of bioconjugation, nanomaterial synthesis, and catalyst immobilization, featuring excellent molecular design flexibility and reaction controllability.

II. [Product Details]
