I. [Product Description]
Mal-PEG-Sodium Alginate is a multifunctional organic intermediate. Through the specific coupling reaction between maleimide groups and thiols, it enables the directional modification of biomolecules. Its unique PEG-sodium alginate composite structure combines excellent water-solubility and biocompatibility. It can be used as a pharmaceutical intermediate to construct functional carrier systems or as a molecular bridging medium in catalytic systems.
