I. [Product Description] 
SS-PEG-OH (Disulfide bond-Polyethylene glycol-Hydroxyl) is a multifunctional organic intermediate, which combines the dynamic reversible cross-linking property of disulfide bonds and the hydrophilicity of PEG chains. It can be used as a pharmaceutical intermediate to construct stimulus-responsive carriers or as a catalyst carrier to optimize reaction systems. Its hydroxyl terminal provides flexible sites for functional modification and is suitable for the precise construction of complex molecular structures.
