I. [Product Introduction]
Vitamin E-PEG-Tosyl is a ternary complex that has undergone functional modification, combining the lipophilic antioxidant properties of vitamin E with the biocompatibility of PEG chains. As a high-performance organic intermediate, its Tosyl active group can efficiently participate in nucleophilic substitution reactions and is widely used in the synthesis of pharmaceutical intermediates and surface functional modification in the preparation of nanocarriers. This compound exhibits excellent structural designability and reaction controllability in catalytic coupling reactions.
