Used as a key intermediate in the synthesis of functional polymers and surface modifiers, particularly in creating hydrophilic coatings and non-ionic surfactants. Its polyether backbone and tertiary amine group enhance solubility in polar solvents and support coordination with metal ions, making it useful in chelating systems and catalysis. Commonly employed in the development of specialty additives for coatings, adhesives, and electronic materials where low volatility and good thermal stability are required. Also finds use in modifying nanoparticle surfaces for improved dispersion in polymer matrices.
