I. [Product Description]
SAS-PEG-Tosylate is a multifunctional organic intermediate. Through the efficient coupling of alkyl sulfonates and tosylate groups, it significantly enhances the solubility and stability of compounds in complex reaction systems. Its unique PEG segment can serve as a flexible spacer arm, which is widely used in the preparation of functional materials and the construction of catalytic systems. It is a key raw material for the synthesis of pharmaceutical intermediates and the development of nanocarriers.
