Description

2,3-Naphtho-18-Crown-6 is a specialized macrocyclic polyether, commonly known as a crown ether, with the CAS number 17454-52-3. This compound is valued for its exceptional ability to form stable complexes with specific cations, particularly potassium ions, due to its precise cavity size and naphtho-substituted structure. It is a critical research and process chemical for scientists and engineers in organic synthesis, catalysis, materials science, and analytical chemistry, where selective ion binding and phase-transfer capabilities are required.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in organic synthesis.
• Ion-Selective Electrodes & Sensors: Serves as a key ionophore in membrane formulations for detecting and measuring potassium ion concentrations.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction processes to selectively separate and purify potassium or similar-sized cations from complex mixtures.
• Supramolecular Chemistry & Host-Guest Systems: Acts as a molecular host for constructing complex architectures and studying non-covalent interactions.
• Polymer & Materials Modification: Incorporated into polymers to create ion-conductive materials or to modify surface properties.
• Analytical Chemistry Reagent: Employed to mask interfering ions or to improve the selectivity of chromatographic and spectroscopic methods.
