Used as a reactive monomer in polymer synthesis, enabling the incorporation of amine functionality into polymers for enhanced adhesion, dye fixation, or bioconjugation. Commonly employed in the production of functional hydrogels, coatings, and copolymers where the primary amine group allows post-polymerization modification. Frequently applied in biomedical materials, drug delivery systems, and as a crosslinking agent in specialty resins. Its hydrochloride salt form improves stability and solubility in aqueous systems during processing.
