Description

4,4(5)-Di(1-Hydroxyheptyl)Dibenzo-18-Crown-6 is a functionalized crown ether derivative, a key compound in supramolecular chemistry and selective ion recognition. Its value lies in its ability to act as a highly selective complexing agent for specific metal cations, particularly potassium and ammonium ions, due to its tailored lipophilic side chains. This makes it an essential material for researchers and manufacturers in advanced chemical synthesis, pharmaceutical development, and sensor technology who require precise molecular recognition and phase-transfer catalysis.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis for alkylation and nucleophilic substitution reactions.
• Ion-Selective Electrodes & Sensors: Serves as a critical ionophore in the membrane of potentiometric sensors for detecting potassium (K⁺) and ammonium (NH₄⁺) ions in analytical and clinical settings.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction processes to selectively separate and concentrate specific metal ions from complex mixtures in hydrometallurgy and environmental analysis.
• Pharmaceutical Intermediate: Employed in the synthesis of more complex macrocyclic compounds or as a building block for drug candidates that require specific ion-binding properties.
• Research & Development: A fundamental tool in academic and industrial R&D for studying host-guest chemistry, molecular recognition, and the development of new functional materials.
• Polymer Modification: Can be incorporated into polymer matrices to create ion-selective membranes or smart materials with responsive properties.

Quality Control

Every batch of 4,4(5)-Di(1-Hydroxyheptyl)Dibenzo-18-Crown-6 is produced and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through comprehensive analytical techniques including HPLC, NMR, and mass spectrometry. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to support your research and 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product performance. Keep away from incompatible materials.
