Description

3,6,9,12,15,18-Hexaoxaicosane is a high-purity polyethylene glycol (PEG) derivative, specifically a symmetrical hexaethylene glycol dimethyl ether. This compound serves as a versatile, aprotic solvent and phase-transfer catalyst with excellent solvating power for cations. It is essential for industries requiring high-boiling, polar reaction media that are compatible with strong bases and various organic substrates, enabling critical synthesis and formulation processes.

Application

• Chemical Synthesis: As a high-boiling, polar aprotic solvent for reactions involving strong bases, organometallic compounds, and anionic polymerizations.
• Phase-Transfer Catalysis (PTC): Employed as a catalyst or co-solvent to facilitate reactions between reagents in immiscible phases, improving yield and efficiency.
• Electrolyte Formulation: Used as a solvent or co-solvent in the preparation of electrolytes for lithium-ion and other advanced battery systems.
• Polymer & Resin Production: Acts as a chain extender, plasticizer, or solvent in the manufacture of polyurethanes, epoxy resins, and other specialty polymers.
• Gas Treatment & Separation: Utilized in formulations for gas scrubbing processes, such as acid gas removal, due to its selective solubility properties.
• Pharmaceutical Intermediates: Serves as a building block or reaction medium in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Specialty Coatings & Inks: Incorporated as a high-boiling solvent to control drying time and improve film formation in performance coatings and printing inks.

Quality Control

Our 3,6,9,12,15,18-Hexaoxaicosane is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and impurity profile are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from strong oxidizing agents.
