1. Temperature
Store Methanesulfonic anhydride in a cool place, preferably around 2 - 8°C (36 - 46°F). This helps maintain its stability and reduces the risk of decomposition or unwanted reactions.
2. Sealed Container
Use an airtight container. It's hygroscopic, meaning Methanesulfonic anhydride CAS 7143-01-3 readily absorbs moisture from the air. A tight seal will prevent moisture from getting in and reacting with the anhydride.
3. Away from Light
Although it's not highly photosensitive, keeping Methanesulfonic anhydride in a dark place or using a light - resistant container can further safeguard its quality over time.
4. Separation from Incompatible Substances
Avoid storing Methanesulfonic anhydride CAS 7143-01-3 near strong oxidizing agents, bases, and water - containing substances. Methanesulfonic anhydride can react violently with these.
