Glycol Ether EE ACS

Product Overview

Glycol Ether EE ACS is a high-purity solvent designed for demanding industrial and analytical environments. This ACS Grade glycol ether exhibits exceptional solvency across a broad range of organic and inorganic substrates while maintaining relatively low volatility. With an assay typical of 99.8% and low residual moisture, it delivers consistent performance in sensitive formulations and analytical workflows. Its clear, colorless liquid appearance, mild ether-like odor, and well-defined physical properties support reliable batch-to-batch consistency in process chemistry, coatings formulations, and HPLC mobile-phase applications. The product is suitable for applications requiring precision, traceability, and adherence to established monographs (ACS Reagent Grade, USP-NF Monograph).

Glycol Ether EE ACS is commonly employed as a versatile solvent in paints and coatings, as a component of HPLC mobile phases, and as a cleaning agent in manufacturing environments. Its miscibility with water and a wide range of organic solvents enables flexible formulation strategies, while controlled impurities and metals levels help minimize interference in analytical and pharmaceutical contexts. The product’s low acidity, refractive index control, and robust storage stability contribute to dependable performance in both laboratory-scale experiments and industrial production lines.

Safety Precautions

Handling and storage should follow established SDS guidelines: store in a cool, dry place away from heat sources and direct sunlight, use HDPE or glass containers, ensure adequate ventilation, and wear appropriate PPE including gloves and safety goggles. Maintain inert atmosphere or reduced moisture exposure to preserve product integrity and minimize moisture-related effects on performance.

In addition, observe exposure controls and emergency procedures: this material is flammable (Flam. Liq. 2) with an SDS signal word of DANGER. Prevent inhalation and skin/eye contact; in case of contact, rinse with water for several minutes and seek medical attention if irritation occurs. If ingested, do not induce vomiting and consult a poison control center or physician. Follow UN 1993 transport regulations for shipping and handling.
