Description

4'-Aminodibenzo-18-Crown-6 is a functionalized crown ether derivative, specifically an amino-substituted benzo-crown ether. This compound is valued for its selective ion-binding capabilities, particularly for alkali and alkaline earth metal cations, which are significantly enhanced by the presence of the primary amine functional group. It serves as a critical complexing agent, phase-transfer catalyst, and chiral selector in advanced chemical synthesis and analytical separations. Key industries that utilize this specialty chemical include pharmaceutical intermediates, academic and industrial research, and sensor technology development.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in nucleophilic substitution and alkylation reactions.
• Ion-Selective Electrodes & Sensors: Acts as an ionophore in the membrane of potentiometric sensors for detecting specific metal ions like potassium or lead.
• Chiral Resolution Agent: Used in the separation of enantiomers via liquid chromatography or as an additive in capillary electrophoresis.
• Metal Ion Extraction & Separation: Employed in solvent extraction processes for the selective recovery or removal of metal cations from complex mixtures.
• Organic Synthesis Intermediate: The primary amine group allows for further derivatization to create more complex crown ether structures or tagged ligands.
• Biomimetic Chemistry & Enzyme Modeling: Used in studies to mimic the function of natural ion channels or transport proteins.
• Polymer Modification: Incorporated into polymer matrices to create ion-selective membranes or smart materials.
• Academic & Industrial R&D: A fundamental research chemical for studying host-guest chemistry, supramolecular assembly, and coordination chemistry.

Quality Control

Our 4'-Aminodibenzo-18-Crown-6 is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Standard quality parameters include identity confirmation, purity assay, and control of specific impurities. Certificates of Analysis (COA) detailing the results of tests such as HPLC, NMR, and elemental analysis are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
