I. [Product Description]
SAS-PEG-His (Alkyl Sulfonate-Polyethylene Glycol-Histidine) is a multifunctional organic intermediate that combines the strong hydrophilicity of sulfonates with the spatial regulation ability of polyethylene glycol (PEG) chains. It can be efficiently applied to the synthesis of pharmaceutical intermediates and catalytic reaction systems. Its histidine group endows the molecule with the potential for directional modification, making it suitable for complex molecular coupling and functional design.
