I. [Product Description] 
NHS-PEG-serine (N-hydroxysuccinimide ester-polyethylene glycol-serine) is a highly efficient organic intermediate. It enables the directional coupling of biomolecules through the active NHS ester group and is widely used in the fields of protein modification and polymer material synthesis. Its unique PEG chain structure can enhance water solubility and improve the reaction efficiency as a catalyst carrier. It is a core functional material for the development of pharmaceutical intermediates.
