Used in polymer chemistry as a functional monomer for synthesizing stimuli-responsive polymers. Its pyridine group enables coordination with metal ions, making it valuable in designing sensors and catalysts. Commonly employed in creating pH-sensitive hydrogels for drug delivery systems due to the nitrogen-containing heterocycle that responds to changes in acidity. Also utilized in the development of molecularly imprinted polymers for selective recognition of analytes in environmental and biomedical applications. Participates in radical polymerization to form copolymers with tailored surface properties, useful in coatings and adhesives.
