Description

4,4(5)-Dicarboxydibenzo-18-Crown-6 is a functionalized crown ether derivative, specifically a dicarboxylated dibenzo-18-crown-6. This compound matters as a highly selective chelating agent and phase-transfer catalyst, prized for its ability to complex with specific metal cations, particularly potassium and cesium ions. It is needed by researchers and manufacturers in pharmaceutical synthesis, analytical chemistry, and materials science for applications requiring precise molecular recognition and separation.

Application

• Ion-Selective Electrodes and Sensors: As a key ionophore in membrane formulations for detecting potassium (K⁺) and cesium (Cs⁺) ions.
• Phase-Transfer Catalysis (PTC): Facilitating reactions between reagents in immiscible phases, particularly useful in organic synthesis.
• Metal Ion Separation and Extraction: Employed in liquid-liquid extraction processes for the selective recovery or removal of specific alkali metal cations from mixtures.
• Chemical Synthesis Intermediate: The carboxylic acid functional groups allow for further derivatization to create novel crown ether-based polymers or complexing agents.
• Analytical Chemistry Reagent: Used as a chiral selector or complexing agent in chromatographic separations and capillary electrophoresis.
• Materials Science Research: A building block for constructing supramolecular structures, molecular machines, and advanced functional materials.
