I. [Product Description]
NH2-PEG-SA (Amino-polyethylene glycol-sialic acid) is a high-performance organic intermediate that combines the high reactivity of amino groups with the specific recognition function of sialic acid. Its core value lies in achieving efficient intermolecular coupling through the tunable PEG chain. It is widely used in the modification of biomaterials and the construction of catalytic systems, and is a key linking module for the development of pharmaceutical intermediates and the synthesis of functional materials.
