Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of dendrimers and hydrogels due to its multiple amine groups. Its high functionality enables efficient network formation in epoxy and polyurethane systems, enhancing mechanical and thermal properties. Also serves as a catalyst and curing agent in resin formulations. Applied in water treatment as a flocculant aid and in personal care products as a viscosity modifier. Shows utility in gene delivery systems as a non-viral vector owing to its ability to condense nucleic acids.
