• CAT Number: I045917
• Molecular Weight: 5000(Average)
• Purity: ≥95%

m-PEG-Triethoxysilane (MW 5000)（Cat No.:I045917）is a methoxy-terminated polyethylene glycol derivative functionalized with a triethoxysilane group for covalent attachment to silica, glass, and metal oxide surfaces. The PEG5000 chain provides excellent hydrophilicity, flexibility, and resistance to protein adsorption, enhancing biocompatibility and reducing nonspecific interactions. The triethoxysilane moiety undergoes hydrolysis and condensation to form stable siloxane linkages, enabling durable surface modification. This reagent is widely applied in nanoparticle coating, biosensor fabrication, medical device functionalization, and material science, where long-chain PEG improves stability, circulation, and antifouling properties in biological and environmental systems.
