Used in polymer chemistry to introduce pyridine functionality into copolymers, enhancing metal coordination and hydrogen bonding capabilities. Commonly applied in the development of functional coatings, sensors, and separation materials due to its ability to interact with metal ions and polar substances. Also utilized in biomedical polymers for drug delivery systems where pH responsiveness is required, leveraging the pyridine ring’s reversible protonation. Serves as a reactive comonomer in dental resins and adhesives, improving mechanical properties and bioactivity through intermolecular interactions.
