Used in the synthesis of stimuli-responsive polymers due to its amine functionality, which can undergo pH-dependent protonation. This property makes it valuable in drug delivery systems where controlled release is required in specific physiological pH environments. Commonly employed in copolymerization with other monomers to create hydrogels and micelles for biomedical applications. Also utilized in surface modification and coating technologies to improve adhesion and biocompatibility. Its reactivity allows for easy integration into polymer networks used in sensors and actuators.
