Description

Benzo-15-Crown-5 is a specialized macrocyclic polyether compound, also known as a crown ether, with the CAS number 14098-44-3. Its primary value lies in its exceptional ability to selectively bind alkali metal cations, particularly sodium ions, making it a powerful and versatile phase-transfer catalyst and complexing agent. This product is essential for researchers and industrial chemists working in advanced organic synthesis, materials science, and analytical chemistry, where precise control over ionic interactions is required.

Application

• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in alkylation, esterification, and polymerization processes.
• Ion-Selective Electrodes & Sensors: Serves as a key ionophore in the membrane of electrochemical sensors for the selective detection and measurement of sodium ions.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction systems to selectively separate and concentrate specific alkali metals from complex mixtures or waste streams.
• Organic Synthesis & Reagent: Enables reactions involving alkali metal salts in non-polar organic solvents by solubilizing the cationic component.
• Polymer & Materials Modification: Incorporated into polymer matrices to create ion-conductive materials or to modify surface properties.
• Analytical Chemistry: Acts as a masking agent or complexant in spectroscopic and chromatographic methods to improve selectivity.
