Quality Control

Our Ethane, 1,1'-Oxybis[2-Fluoro- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including GC, NMR, and Karl Fischer titration to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and strong acid/organic solvent nature, it should be kept separate from strong oxidizers and bases. Recommended storage temperature is 2-8°C to maximize shelf-life stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
