Quality Control

Our Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With Butanediol (2:1) is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for hydroxyl value, viscosity, water content, and purity. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
