Used in the synthesis of functional polymers and copolymers, particularly in the production of cationic resins for water treatment and paper manufacturing. Acts as a reactive monomer in specialty coatings and adhesives due to its ability to form cross-linked networks, including corrosion-resistant coatings. Employed in the development of pharmaceutical intermediates, antimicrobial agents, and controlled drug delivery systems. Also utilized in the preparation of ion-exchange materials, separation processes, and as a modifier in cosmetic formulations for hair and skin care products due to its conditioning properties. Additionally, valued for its metal-binding capabilities and as a component in catalytic systems with low solvent use, enabling catalyst recycling in the chemical industry. Its polymers exhibit adjustable water solubility and responsiveness to environmental stimuli such as pH.
