Used as a surface modifier in drug delivery systems, enabling targeted release by functionalizing nanoparticles for improved biocompatibility and cellular uptake. Commonly applied in chromatography stationary phases to enhance selectivity for polar compounds. Serves as a coupling agent in composites, improving adhesion between organic and inorganic materials. Widely utilized in biosensors for immobilizing biomolecules like enzymes or DNA due to its reactive amine groups. Also employed in catalysis support, where the amine functionality helps anchor metal catalysts, increasing stability and reusability.
