Description

4-Sulfocalix[4]Arene Sodium Salt is a water-soluble, anionic derivative of calixarene, a versatile macrocyclic host molecule. This compound matters for its exceptional ability to form stable complexes with various cations and organic molecules, making it a powerful supramolecular building block and analytical reagent. Industries requiring selective binding, sensing, or separation technologies, such as pharmaceuticals, environmental science, and materials research, need this specialized chemical.

Application

• Ion-Selective Electrodes & Sensors: Acts as an ionophore for creating selective membranes to detect specific metal ions (e.g., lead, cadmium, cesium) in analytical and environmental monitoring.
• Pharmaceutical Research & Drug Delivery: Utilized as a host molecule to improve the solubility, stability, and bioavailability of active pharmaceutical ingredients (APIs) through encapsulation.
• Wastewater Treatment & Metal Recovery: Employed in extraction processes to selectively bind and remove toxic heavy metals or recover valuable rare earth elements from industrial effluents.
• Catalysis & Organic Synthesis: Serves as a phase-transfer catalyst or a nanoreactor scaffold due to its well-defined cavity, facilitating reactions in aqueous or biphasic systems.
• Chromatography & Separation Science: Used as a stationary phase modifier or a chiral selector in HPLC and capillary electrophoresis for the separation of enantiomers and isomers.
• Nanomaterial & Polymer Modification: Functionalizes surfaces or polymers to introduce sulfonate groups, enhancing hydrophilicity, ionic conductivity, or specific binding properties.
