Description

1,4,7,12,15,18-Hexaoxacyclodocosane-8,11,19,22-Tetrone CAS NO 77022-93-6 is a complex macrocyclic polyether compound, also known as a crown ether derivative, characterized by its specific cavity size and oxygen donor atoms. This structure is critical for its ability to selectively bind cations, making it a valuable tool for phase-transfer catalysis and molecular recognition. It is primarily utilized by researchers and manufacturers in advanced organic synthesis, analytical chemistry, and materials science for creating selective ionophores and facilitating challenging chemical transformations.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in organic synthesis.
• Ionophore for Sensor Development: Serves as a key component in the design of ion-selective electrodes (ISEs) and optical sensors for detecting specific metal ions.
• Molecular Recognition Studies: Used in supramolecular chemistry research to study host-guest interactions and develop novel molecular assemblies.
• Metal Ion Extraction & Separation: Employed in liquid-liquid extraction processes to selectively separate and purify valuable or toxic metal ions from complex mixtures.
• Polymer Modification: Can be incorporated into polymer matrices to create materials with specific ion-binding or transport properties.
• Analytical Chemistry Reagent: Used as a complexing agent to mask interfering ions or enhance the selectivity of analytical methods like chromatography.
