I. [Product Description] 
SAS-PEG-Tryptophan (Alkyl Sulfonate-Polyethylene Glycol-Tryptophan) is a multifunctional organic intermediate that combines the hydrophilicity of sulfonates and the biocompatibility of tryptophan. Precise molecular weight control can be achieved through the PEG chain. This compound exhibits excellent stability and modifiability in the synthesis of pharmaceutical intermediates and catalytic reaction systems, and is suitable for the directional assembly of complex molecular structures.
