I. [Product Description]
NHS-PEG-P4VPN-N-hydroxysuccinimide ester-polyethylene glycol-poly(4-vinylpyridine) is a multifunctional organic intermediate that combines the biocompatibility of polyethylene glycol (PEG) with the catalytic properties of poly(4-vinylpyridine) (P4VPN). It is suitable for the fields of bioconjugation and polymer synthesis. The NHS ester group in its structure enables efficient and specific conjugation, while the P4VPN module endows it with unique pH responsiveness and catalytic functions. It is an ideal choice for the development of pharmaceutical intermediates and materials science research.
