I. [Product Description]
Casein-PEG-HZ (Casein-Polyethylene Glycol-Hydrazide) is a multifunctional organic intermediate that enables efficient coupling reactions through the hydrazide group. It is widely used in protein modification and the development of biomaterials. Its core value lies in combining the natural stability of casein and the biocompatibility of PEG chains. It is suitable for drug delivery systems and as a catalyst carrier in the synthesis of polymer materials, with both precise molecular weight controllability and reaction site specificity.
