Description

4,4(5)-Didecyldibenzo-18-Crown-6 is a lipophilic, substituted crown ether derivative, specifically a member of the dibenzo-18-crown-6 family. This compound matters for its exceptional ability to selectively complex with specific cations, particularly potassium ions, making it a powerful phase-transfer catalyst and ionophore in non-aqueous systems. Industries requiring advanced separation science, chemical synthesis, and materials research need this high-purity reagent for its predictable and efficient performance in creating controlled ionic environments.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between ionic reagents and organic substrates in biphasic systems, enhancing reaction rates and yields in organic synthesis.
• Ion-Selective Electrodes (ISEs): Serves as a critical ionophore in membrane formulations for potentiometric sensors targeting potassium and other cations.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction processes for the selective separation, recovery, or purification of alkali and alkaline earth metals from complex mixtures.
• Polymer & Materials Science: Incorporated into polymeric membranes and materials to impart ion-conducting or ion-selective properties.
• Analytical Chemistry: Employed as a chiral selector or complexing agent in chromatographic separations and capillary electrophoresis.
• Fundamental Research: A key tool in supramolecular chemistry studies for investigating host-guest interactions and molecular recognition phenomena.
