Used as a key monomer in the synthesis of functional polymers, particularly in the development of pH-responsive hydrogels and ion-sensitive materials. Its carboxylic acid groups enable ionic interactions and crosslinking, making it valuable in drug delivery systems where controlled release is required. Commonly employed in biomedical applications such as tissue engineering scaffolds and contact lenses due to its hydrophilic nature and biocompatibility. Also utilized in coatings and adhesives to improve adhesion to metal and mineral surfaces through chelation. Its methacrylamide group allows for easy copolymerization with other vinyl monomers via radical polymerization, enabling tailored polymer architectures for specialty materials.
