I. [Product Description] 
SAS-PEG-Valine (Alkyl Sulfonate-Polyethylene Glycol-Valine) is a multifunctional organic intermediate with both amphiphilic structure and tunable molecular weight characteristics. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalytic systems. The synergistic effect of its unique sulfonic acid group and PEG segment significantly enhances the solubility and reactivity of the compound, making it suitable for complex molecular modification and functional material development.
