I. [Product Description]
SAS-PEG-VS (Alkyl Sulfonate-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate that combines high-efficiency catalytic activity with biocompatibility. It is widely used in the preparation of pharmaceutical intermediates and the synthesis of polymer materials. Its unique vinyl sulfone group and adjustable PEG chain length enable precise coupling reactions, which are of great value in nanodrug delivery systems and functional surface modification.
