I. [Product Description]
Epoxides-PEG-SH is a multifunctional organic intermediate that combines the high reactivity of epoxides, the hydrophilicity of PEG chains, and the directional coupling ability of sulfhydryl groups. It is widely used in the crosslinking of polymer materials, the surface modification of nanoparticles, and the construction of catalytic systems. As a pharmaceutical intermediate and catalyst carrier, it can significantly enhance the stability and functionalization efficiency of materials.
