I. [Product Description]
HSA-PEG-HZ is a high-molecular organic intermediate covalently modified by human serum albumin (HSA) and polyethylene glycol (PEG) through a hydrazide bond (HZ). It combines biocompatibility and chemical controllability, and is suitable for functional modification in biological coupling reactions and the preparation of composite materials. As a pharmaceutical intermediate, it can efficiently promote the directional coupling of active molecules and carriers. Meanwhile, the introduction of the PEG chain significantly enhances the water solubility and stability of the product, showing excellent performance in the catalytic reaction system.
