I. [Product Description]
SA-PEG (Sialic acid-Polyethylene glycol) is a high-purity organic intermediate that combines the targeted recognition function of sialic acid with the biocompatibility advantage of PEG. It is widely used in the synthesis of pharmaceutical intermediates and the construction of carriers for biocatalysts. Its unique molecular structure can effectively improve the water solubility of materials and provide active sites for subsequent functional modification.
