Used as a specialty solvent and intermediate in organic synthesis, particularly in the preparation of surfactants and lubricant additives. Its long alkoxy chains provide good solubility in nonpolar media, making it suitable for applications in fuel and oil formulations where it can act as a dispersant or stabilizer. Also employed in the development of thioether-based functional materials due to the reactive sulfur center, which can participate in oxidation or coordination reactions. Limited use in polymer modification to enhance flexibility and environmental stability.
