Used as a reactive diluent in epoxy resin systems to reduce viscosity and improve workability without sacrificing performance. Enhances flexibility and impact resistance of cured epoxy formulations. Commonly applied in coatings, adhesives, sealants, and composite materials where low volatility and good compatibility are required. Also utilized in the modification of polymers and as a crosslinking agent in specialty resins. Its hydrophilic nature makes it suitable for applications requiring water solubility or moisture resistance.

Additionally, it is used in biomedical research and biotechnology, such as in the creation of hydrogels for controlled drug release or as a linker in targeted drug delivery systems, due to its biocompatibility and ability to tailor material properties.

In polymer manufacturing processes, it helps control viscosity and extend the pot life of mixtures before curing, facilitating easier production control.
