Description

N,N'-Bis(Methoxymethyl)Diaza-15-Crown-5, 98 is a high-purity, functionalized crown ether derivative, specifically a diaza-crown ether with methoxymethyl pendant arms. This compound matters as a versatile and selective complexing agent for metal cations, particularly valuable for its ability to bind and transport ions in non-aqueous media and act as a phase-transfer catalyst. It is primarily needed by researchers and manufacturers in advanced organic synthesis, materials science, and analytical chemistry for developing sensors, catalysts, and separation technologies.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in alkylation and other organic syntheses.
• Ionophore for Chemical Sensors: Serves as a key sensing component in ion-selective electrodes (ISEs) and optodes for detecting specific alkali and alkaline earth metal ions.
• Metal Ion Extraction & Separation: Used in solvent extraction processes for the selective recovery, purification, or removal of target metal ions from complex mixtures.
• Supramolecular Chemistry Building Block: Acts as a precursor or host molecule for constructing more complex molecular machines, switches, and functional assemblies.
• Polymer Modification: Incorporated into polymer matrices to create ion-conductive membranes or materials with specific metal-binding properties.
• Analytical Chemistry Reagent: Employed as a masking agent or complexant in titrations, chromatography, and spectroscopic analysis to improve selectivity.
