Used as a crosslinking agent in polymer synthesis, particularly in epoxy resins and polyurethanes, enhancing thermal stability and mechanical strength. Acts as a curing agent in coatings, adhesives, and composites due to its multifunctional amine structure. Employed in the preparation of dendrimers and other branched macromolecules for drug delivery and nanotechnology applications. Also serves as a building block in the synthesis of specialty amines and ligands for catalysis and metal chelation.
