Quality Control

Our S,S-Difluoro-n-Methylsulfimine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR analysis, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters such as assay and impurity profiles. Our quality commitment ensures the material meets the high standards required for research and process chemistry applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its reactivity as a fluoride/strong alkali, it should be kept separate from incompatible materials such as strong acids and moisture. Recommended storage temperature is 2-8°C for long-term stability. Handle and store under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation.
