I. [Product Description]
VS-PEG-Silane (Vinyl Sulfone-Polyethylene Glycol-Silane) is a multifunctional organic intermediate that combines the high reactivity of vinyl sulfone groups, the hydrophilicity of PEG segments, and the immobilization properties of silane groups. It is widely used in bioconjugation, material surface modification, and the preparation of nanocarriers. As an efficient crosslinking agent and interface modifier, it exhibits excellent stability and controllability in catalytic coupling reactions and is a core raw material for the synthesis of pharmaceutical intermediates and the development of functional materials.
