Used as a curing agent and crosslinking agent in epoxy resin systems, enhancing flexibility and adhesion in coatings, adhesives, and composites. Its ether linkages provide improved hydrolytic stability and moisture resistance, making it suitable for applications in electronics encapsulation and structural bonding. Also employed in the synthesis of specialty polyurethanes and as a building block in chelating agents due to its amine functionality and hydrophilic spacer structure.
