Used as a crosslinking agent in polymer chemistry, particularly in the production of epoxy resins and polyurethanes, enhancing thermal stability and mechanical strength. It serves as a building block in the synthesis of specialty polyamides and polyimides for high-performance materials. Also applied in the development of biocidal coatings and antimicrobial surfaces due to its amine functionality. In research, it acts as a precursor for dendrimers and other branched macromolecules used in drug delivery systems. Its multiple amine groups make it effective in chelating metal ions, useful in water treatment and catalysis applications.
