Quality Control

Our Decaethylene Glycol Monomethyl Ether is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications for high-purity applications. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
