Description

Benzo-18-Crown-6 is a highly selective macrocyclic polyether, also known as a crown ether, with the CAS number 14098-24-9. Its unique cavity size makes it an exceptional phase-transfer catalyst and complexing agent for alkali metal cations, particularly potassium. This compound is essential for researchers and manufacturers in advanced chemical synthesis, analytical chemistry, and materials science who require precise control over reaction kinetics and ion selectivity.

Application

• Phase-Transfer Catalysis (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 electrodes for the potentiometric detection of potassium and other cations.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction processes to selectively separate and purify specific alkali and alkaline earth metals from complex mixtures.
• Polymer & Materials Science: Acts as a template or additive in the synthesis of functional polymers and advanced materials with tailored ionic properties.
• Analytical Chemistry: Employed as a masking agent or complexant in titrations, chromatography, and spectroscopic analysis to improve selectivity.
• Biomimetic Chemistry & Enzyme Modeling: Used to model the cation-binding sites of enzymes and study cation transport mechanisms.
