Used in dental and biomedical materials as a reactive monomer that enhances adhesion to mineralized tissues like enamel and dentin. Its phosphate group binds strongly to calcium in tooth structures, making it effective in dental adhesives, restorative composites, and cements. Also employed in bone-targeting drug delivery systems and coatings for implants due to its affinity for hydroxyapatite. The methacrylate functionality allows it to copolymerize with other resin components, enabling integration into light-cured or self-cured polymer networks.
