I. [Product Description] 
VS-PEG-SA (Vinyl Sulfone-Polyethylene Glycol-Stearic Acid) is a multifunctional organic intermediate with dual characteristics of a pharmaceutical intermediate and a catalyst carrier. The vinyl sulfone group in its molecular structure provides high-efficiency coupling activity, the PEG chain enhances water solubility and biocompatibility, and the hydrophobic end of stearic acid imparts self-assembly ability, making it suitable for complex chemical modification and the development of functionalized materials.
