Used in polymer chemistry as a functional monomer for creating stimuli-responsive materials due to its ability to form hydrogen bonds and coordinate with metal ions. Employed in the development of sensors, where its structure enhances selectivity and sensitivity toward metal ion detection. Applied in drug delivery systems because of its biocompatibility and pH-responsive behavior in physiological environments. Also utilized in corrosion inhibitors for metals, leveraging its nitrogen-containing heterocyclic group to adsorb onto metal surfaces. Investigated for use in conductive polymers and coatings, where it contributes to improved thermal and chemical stability.
