Quality Control

Our 1,1-Difluorodimethyl Ether is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the precise requirements of our industrial and research partners. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 2°C and 8°C to minimize vapor pressure and maintain stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
