I. [Product Description]
Tosylate-Polyethylene Glycol-Stearic Acid (Tosylate-PEG-SA) is an amphiphilic organic intermediate containing active tosylate groups. It combines the water-solubility of the PEG segment and the hydrophobic properties of stearic acid. It can be used as a key linking molecule for pharmaceutical intermediates or surface modification of polymer materials. Its tosylate group can achieve efficient nucleophilic substitution reactions, and the molecular weight of PEG can be customized to meet different application requirements.

II. [Product Details]
