Used as a curing agent or crosslinking agent in epoxy resin systems, enhancing thermal stability and mechanical strength of the final product. Its aliphatic amine structure allows for controlled reactivity, making it suitable for coatings, adhesives, and composite materials where extended working time and durability are required. Also employed in the synthesis of specialty polymers and as an intermediate in the production of pharmaceuticals and agrochemicals due to its defined stereochemistry and functional group compatibility.
