Used as a coupling agent in advanced material synthesis, particularly in modifying surfaces of silica and glass for improved adhesion in composite materials. Enhances durability and stability in coatings, sealants, and adhesives by forming strong bonds between organic polymers and inorganic substrates. Also applied in the development of functionalized nanoparticles for drug delivery systems and biosensors due to its ability to link biomolecules to carrier surfaces. Its multi-ethoxy chain provides flexibility and water solubility, making it suitable for use in aqueous environments and biomedical applications.
