Quality Control

Our 1,3-Dioxolane-2,2-Diethanol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from strong oxidizing agents.
