Quality Control

Our 2-Ethyl-4-Methyl-1,3-Dioxolan is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting key parameters such as assay (by GC), water content, and isomeric ratio are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
