Used as a macrocyclic ligand in coordination chemistry, particularly for binding alkali and alkaline earth metal ions. Its structure allows selective complexation, making it useful in ion transport studies and sensor development. Employed in research for designing ionophores in membrane-based systems such as ion-selective electrodes. Also explored in supramolecular chemistry for creating host-guest complexes due to its cavity size and oxygen donor atoms. Shows potential in catalysis and molecular recognition applications.
