Description

4,13-Diaza-18-Crown 6-Ether is a specialized macrocyclic polyether compound, also known as a diaza-crown ether, valued for its exceptional ability to selectively bind cations, particularly alkali and alkaline earth metal ions. This selective complexation property makes it a critical tool in chemical synthesis, separation science, and analytical chemistry. It is primarily utilized by researchers and manufacturers in the pharmaceutical, chemical research, and material science industries for applications such as phase-transfer catalysis, ion transport studies, and sensor development.

Application

• Phase-Transfer Catalyst: Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in organic synthesis.
• Ion-Selective Electrodes & Sensors: Serves as an ionophore in the membrane of sensors for detecting specific metal ions like potassium or sodium.
• Metal Ion Separation & Extraction: Used in liquid-liquid extraction processes to selectively separate and purify specific metal ions from complex mixtures.
• Biomimetic Chemistry & Enzyme Modeling: Acts as a model for studying natural ion transport processes across cell membranes.
• Chemical Research Reagent: Employed in academic and industrial R&D for studying host-guest chemistry and supramolecular assembly.
• Polymer Modification: Can be incorporated into polymers to create materials with specific ion-binding or transport properties.

Quality Control

Our 4,13-Diaza-18-Crown 6-Ether is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets high-purity research and industrial standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture absorption.
