Used as a specialty crosslinking agent in polymer chemistry, particularly in the synthesis of polyurethanes and polyureas. Its structure contains multiple protected amine groups that can be deprotected under mild conditions to release primary amines, enabling controlled stepwise reactions in complex macromolecule assembly. Commonly applied in pharmaceutical intermediates and functional coatings where precise molecular architecture is required. Also utilized in the development of stimuli-responsive materials due to its acid-labile tert-butoxycarbonyl (Boc) groups, allowing triggered deprotection in acidic environments. Suitable for advanced material design including drug delivery systems and smart hydrogels.
