I. [Product Description] 
Casein-PEG-SS is an organic intermediate based on the coupling of casein and polyethylene glycol (PEG) through a disulfide bond (SS). It has excellent biocompatibility and controllable degradation characteristics. This compound can be used as a pharmaceutical intermediate or a catalyst carrier. Its disulfide bond structure supports reductive responsive cleavage and is suitable for the construction of functionalized materials and the development of targeted delivery systems.
