This chemical is primarily used as a reactive intermediate in organic synthesis, particularly in the modification of polymers and the preparation of functionalized materials. It is often employed in the development of hydrophilic coatings, where its structure allows for the introduction of ethylene oxide units into various substrates, enhancing their water solubility or compatibility. Additionally, it serves as a key component in the synthesis of surfactants and emulsifiers, contributing to the stabilization of emulsions and improvement of surface properties in industrial formulations. Its ability to act as a sulfonate ester makes it valuable in crosslinking reactions and the production of specialized polymers with tailored properties.
