Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of dendrimers and porous organic frameworks. Its trifunctional amine structure allows for the formation of three-dimensional network polymers when reacted with suitable electrophilic monomers. Commonly employed in the development of covalent organic frameworks (COFs) for gas storage, catalysis, or sensing applications due to its symmetrical geometry and reactive sites. Also finds use in surface functionalization of nanomaterials where controlled amine presentation is required. The hydrochloride form enhances solubility in polar solvents, facilitating its use in aqueous or mixed solvent systems.
