Ethylene Glycol ACS Grade

Product Overview

Ethylene Glycol, ACS Grade (C₂H₆O₂), is a high-purity, colorless, hygroscopic liquid widely utilized in industrial and laboratory environments. Commonly referred to as MEG (Monoethylene Glycol) or industrial antifreeze, this solvent is characterized by its slightly sweet odor and excellent miscibility with water and organic solvents.

This ACS-grade material is manufactured to meet strict specifications for assay purity (typically 99.8%) and extremely low water content (typical 0.02%). These properties make it an essential reagent for analytical applications where trace contaminants must be minimized. Beyond laboratory use, it serves as a reliable heat transfer fluid and a versatile intermediate in chemical processing. Its physical properties—including a high boiling point of 197.3°C and low freezing point—ensure stability across a wide range of operating temperatures.

• Laboratory Reagent: Serves as a high-purity solvent and reagent in analytical chemistry and chromatographic preparations requiring ACS-grade specifications.
• Chemical Synthesis: Acts as a raw material and solvent in the manufacturing of polyesters, resins, and various organic compounds.
• Industrial Solvent: Effective solvent for paints, lacquers, and dyes due to its low volatility and miscibility properties.

Safety & Handling

Storage and handling of Ethylene Glycol ACS Grade should adhere to established chemical hygiene protocols. Store in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials such as strong oxidizers and strong acids. Suitable storage containers include HDPE or glass.

Safety Precautions: Wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Do not ingest. In the event of exposure, rinse affected areas thoroughly with water and seek medical attention if symptoms persist. Always consult the Safety Data Sheet (SDS) for detailed safety, disposal, and emergency information before use.
