Used as a curing agent in epoxy resin systems, enhancing mechanical strength and flexibility. Its amine functionality allows for cross-linking with epoxide groups, making it suitable in coatings, adhesives, and composite materials. Also employed in synthesizing specialty polymers and as a building block in pharmaceutical intermediates due to its bifunctional structure. Shows utility in gas treatment as an absorbent for acid gases like CO₂ and H₂S. Additionally, serves in the formulation of surfactants and corrosion inhibitors.
