Description

4',4''(5'')-Di-tert-Butyldicyclohexano-18-Crown-6 is a specialized crown ether derivative, a member of the dicyclohexano-18-crown-6 family, known for its exceptional selectivity in complexing with specific cations. This compound matters for its enhanced lipophilicity and steric bulk provided by the tert-butyl substituents, which significantly improve its extraction efficiency and phase-transfer catalytic properties in non-aqueous systems. It is critically needed by R&D chemists and process engineers in the pharmaceutical, nuclear fuel reprocessing, and specialty chemical synthesis industries for applications requiring high-purity separation and catalysis.

Application

• Selective Cation Extraction: Used as a highly selective extractant for potassium, strontium, and lead ions in solvent extraction processes, particularly in nuclear waste treatment and metal recovery.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, accelerating alkylation, esterification, and other synthesis steps in pharmaceutical and fine chemical manufacturing.
• Ion-Selective Electrodes & Sensors: Serves as a key ionophore in the membrane of electrochemical sensors for detecting specific cations in analytical and environmental monitoring.
• Purification of Pharmaceuticals: Employed in the purification of chiral amines and other pharmaceutical intermediates through selective complexation.
• Fundamental Chemical Research: A vital tool in supramolecular chemistry and host-guest interaction studies for modeling biological ion transport.
• Radioactive Isotope Separation: Critical in the separation and recovery of strontium-90 and other radioactive isotopes in nuclear chemistry applications.
