Used primarily in the synthesis of cationic polymers for water treatment processes, this chemical aids in the flocculation and removal of negatively charged impurities, organic matter, proteins, and nucleic acids from wastewater. It is a key monomer in producing polyelectrolytes used in municipal and industrial water purification systems.

Commonly employed in the paper industry to improve dry strength and retention during papermaking by enhancing fiber bonding and adhesion of additives.

Applied in the formulation of antimicrobial coatings and surfaces due to the biocidal properties of quaternary ammonium groups, which disrupt bacterial cell membranes, making it suitable for use in medical devices, textiles, and hygiene products.

Also utilized in the development of contact lens materials and other biomedical applications where controlled hydrophilicity and ionic interactions are required.

In personal care products, such as shampoos and conditioners, it contributes to polymer formulations that coat hair, improve smoothness, reduce static, and enhance surface properties.

Its reactive methacrylate group allows for easy copolymerization with other vinyl monomers, enabling tailored polymer design for specific industrial and pharmaceutical applications.
