I. [Product Description]
Fmoc-NH-PEG-NH2∙TFA is a highly reactive organic intermediate with both pharmaceutical intermediate and polymer material modification functions. Its core value lies in achieving efficient intermolecular coupling through the controllable PEG (polyethylene glycol) chain. Meanwhile, the fluorenylmethyloxycarbonyl (Fmoc) and NHS ester groups provide key connection sites for peptide synthesis and bioconjugation reactions.
