Description

4,4(5)-Ditetradecyldibenzo-18-Crown-6 is a lipophilic, substituted crown ether derivative, specifically a member of the dibenzo-18-crown-6 family. This compound is valued for its exceptional ability to selectively complex with alkali and alkaline earth metal cations, particularly potassium ions, in non-aqueous and membrane systems. It is a critical material for researchers and manufacturers in advanced separation technologies, ion-selective electrode development, and as a phase-transfer catalyst in organic synthesis.

Application

• Ion-Selective Electrodes (ISEs): Serves as a highly selective ionophore in polymeric membrane electrodes for the potentiometric detection of potassium and other cations.
• Membrane Transport & Separation: Used in supported liquid membranes (SLMs) and polymer inclusion membranes (PIMs) for the selective extraction and transport of metal ions from complex mixtures.
• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible phases (e.g., aqueous and organic) by solubilizing inorganic salts in organic media.
• Chemical Sensors & Biosensors: A key component in the development of chemical sensors for environmental monitoring and clinical analysis.
• Fundamental Coordination Chemistry Research: Employed in studies of host-guest chemistry, cation binding kinetics, and supramolecular assembly.
• Analytical Chemistry: Used as a chiral selector or complexing agent in chromatographic separations and capillary electrophoresis.
