trimethyloxonium tetrafluoroborate(CAS: 420-37-1)

Trimethyloxonium tetrafluoroborate is a chemical compound with the formula (CH3O)3NBF4. It is a colorless to white crystalline solid with a pungent odor. It is highly soluble in water and organic solvents.

Trimethyloxonium tetrafluoroborate is mainly used as a reagent in organic synthesis, particularly in the preparation of triflates through a reaction with triflic anhydride. It is also used in the synthesis of various pharmaceutical and agrochemical compounds due to its Lewis acidity and reactivity.

Trimethyloxonium tetrafluoroborate is generally considered safe for laboratory use when handled with appropriate precautions. It is not considered flammable or explosive, but it can cause skin and eye irritation. Protective measures include wearing gloves, goggles, and protective clothing. It should be stored away from heat and sources of ignition.

Trimethyloxonium tetrafluoroborate should be stored in a cool, dry place away from direct sunlight and heat sources. It should be stored in a tightly sealed container to prevent moisture absorption. The storage temperature should be below 25°C to ensure stability and prevent degradation.
