Used in drug delivery systems to enhance solubility and controlled release of poorly water-soluble drugs. Acts as a building block in click chemistry for creating targeted supramolecular complexes. Applied in biosensors and diagnostic tools due to its ability to form host-guest complexes and attach to biomolecules via azide group. Employed in surface modification of nanoparticles and polymers for biomedical applications. Also utilized in enzyme mimics and separation science for selective molecular recognition.
