Description

Hexaethylene Glycol is a high-purity, water-soluble polyethylene glycol derivative, valued for its excellent solvency and chemical stability. This compound serves as a crucial intermediate and functional additive in advanced manufacturing processes, where precise molecular weight and purity are paramount. It is essential for industries such as pharmaceuticals, specialty polymers, and high-performance lubricants, where its defined oligomeric structure provides consistent performance.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, linkers for antibody-drug conjugates (ADCs), and as a solubilizing agent in formulations.
• Polymer & Resin Production: Acts as a monomer or chain extender in the manufacture of polyurethanes, polyesters, and other specialty polymers.
• Lubricant & Functional Fluid Additive: Imparts viscosity control, thermal stability, and moisture resistance in synthetic lubricants and hydraulic fluids.
• Surface Active Agent: Functions as a non-ionic surfactant or wetting agent in coatings, inks, and agrochemical formulations.
• Chemical Synthesis & Cross-linking: Serves as a spacer or building block in organic synthesis and as a cross-linking agent for resins.
• Gas Dehydration & Treatment: Utilized as a hygroscopic agent in natural gas drying and acid gas removal processes.

Quality Control

Our Hexaethylene Glycol is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere (e.g., nitrogen) to minimize potential oxidation.
