Used as a solvent and chemical intermediate in organic synthesis, particularly in the production of specialty polymers and surfactants. Its multiple ether groups and hydroxyl end group provide good solvency for polar and nonpolar substances, making it useful in coatings, inks, and cleaning formulations. It is also employed in the synthesis of functionalized polymers and as a building block in pharmaceuticals due to its ability to link hydrophilic segments. Additionally, it finds use in electroplating baths and as a modifier in resin systems to improve flexibility and adhesion.
