Quality Control

Our production of Propanol, Oxybis(Methyl-2,1-Ethanediyl)Oxybis- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistency, purity, and compliance with customer specifications. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and color are available upon request to support your quality assurance processes.

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, containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong alkalis and incompatible materials.
