Description

4,4(5)-Di(1-Hydroxydecyl)Dibenzo-18-Crown-6 is a functionalized crown ether derivative, specifically a lipophilic dibenzo-18-crown-6 ether with long-chain hydroxymethyl substituents. This molecular design is critical for creating highly selective phase-transfer catalysts and complexing agents, particularly for alkali and alkaline earth metal cations. It is essential for researchers and manufacturers in advanced organic synthesis, materials science, and analytical chemistry who require precise molecular recognition and separation capabilities.

Application

• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible phases, enhancing reaction rates and yields in alkylation, oxidation, and polymerization processes.
• Ion-Selective Electrodes & Sensors: Serves as a key ionophore in the membrane of electrochemical sensors for detecting potassium, sodium, or ammonium ions.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction systems for the selective recovery, purification, or removal of specific metal ions from complex mixtures.
• Advanced Material Synthesis: A building block for synthesizing supramolecular polymers, dendrimers, and functionalized surfaces with tailored host-guest properties.
• Pharmaceutical Intermediate: Employed in the synthesis of complex drug molecules where selective cation binding is required for a specific synthetic step.
• Analytical Chemistry: Acts as a chiral selector or complexing agent in chromatographic separations (HPLC, CE) for enantiomeric resolution or ion analysis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
