I. [Product Description]
Tosyl-PEG-SA is a multifunctional organic intermediate. It enables precise coupling through the activation of end groups by tosyl groups, and the hydrophobic chain of stearic acid imparts amphiphilic characteristics to the material. This compound exhibits high catalytic activity in the construction of nanocarriers and the modification of polymers, and is particularly suitable for the synthesis of pharmaceutical intermediates and the development of functional materials.
