Used as a selective ionophore in chemical sensors and ion-selective electrodes, particularly for detecting alkali and alkaline earth metal ions due to its high binding affinity. Its structure enables effective complexation with potassium ions, making it valuable in analytical chemistry for ion detection and separation processes. Also employed in supramolecular chemistry for designing host-guest systems and molecular recognition studies. Shows potential in membrane transport systems for facilitating ion transfer across lipid bilayers, useful in drug delivery and catalysis research.
