I. [Product Description]
SS-PEG-Tryptophan is a polyethylene glycol-tryptophan complex containing a dynamic cross-linking structure with disulfide bonds. As a high-performance organic intermediate and pharmaceutical intermediate, it combines the hydrophilicity of the PEG chain, the biocompatibility of tryptophan, and the responsive cleavage property of disulfide bonds. It is suitable for fields such as drug delivery systems, biomaterial modification, and catalyst carrier construction.
