Description

4,4(5)-Di(1-Hydroxyoctadecyl)Dibenzo-18-Crown-6 is a lipophilic, long-chain alkyl-substituted crown ether derivative. This compound is valued for its exceptional ability to selectively complex with specific metal cations, particularly potassium, in non-aqueous or low-polarity environments. It is primarily needed by researchers and manufacturers in advanced materials science, chemical synthesis, and analytical chemistry for applications requiring phase-transfer catalysis or selective ion extraction.

Application

• Phase-Transfer Catalyst: Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis involving alkali metal salts.
• Ion-Selective Electrodes (ISEs): Serves as a critical ionophore in membrane formulations for detecting potassium and other specific cations.
• Chemical Sensors & Probes: Used in the development of fluorescent or colorimetric sensors for metal ion detection in research and environmental monitoring.
• Liquid-Liquid Extraction: Enables the selective separation and pre-concentration of target metal ions from complex mixtures.
• Polymer Modification: Incorporated into polymer matrices to create ion-selective membranes or materials with tailored transport properties.
• Supramolecular Chemistry Research: Acts as a building block for constructing complex host-guest systems and molecular machines.
• Analytical Chemistry: Employed as a chiral selector or complexing agent in chromatographic separations.
