Description

[3,5!-Dibenzo-24-Crown-8, 98 is a high-purity, synthetic macrocyclic polyether belonging to the crown ether family, specifically a dibenzo-substituted 24-crown-8 derivative. This compound is valued for its exceptional ability to selectively bind alkali and alkaline earth metal cations, making it a critical component in supramolecular chemistry, catalysis, and advanced materials science. It is primarily utilized by researchers and industrial chemists in the development of molecular sensors, phase-transfer catalysts, and novel separation membranes.

Application

• Supramolecular Chemistry & Host-Guest Systems: Acts as a key building block for constructing rotaxanes, catenanes, and other mechanically interlocked molecules due to its large cavity and strong binding affinity for specific cations.
• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis for anion activation and improving reaction rates and yields.
• Ion-Selective Electrodes & Sensors: Serves as an ionophore in the membrane of electrochemical sensors for the selective detection and quantification of potassium, ammonium, and other cations.
• Metal Ion Extraction & Separation: Employed in liquid-liquid extraction processes to selectively separate and recover valuable or toxic metal ions from complex mixtures.
• Polymer & Materials Science: Incorporated into polymers to create ion-conductive materials, self-healing gels, or smart materials with stimuli-responsive properties.
• Analytical Chemistry: Used as a chiral selector or complexing agent in chromatographic techniques like HPLC and capillary electrophoresis for enantiomer separation.

Quality Control

Our [3,5!-Dibenzo-24-Crown-8, 98 is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and NMR for structural confirmation, to ensure it meets the specified 98% minimum purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency for your research and development needs.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from strong oxidizing agents.
