FAQ

What is Trifluoromethanesulfonic Anhydride (CAS: 358-23-6)?

Trifluoromethanesulfonic Anhydride is a strong organic sulfonic acid anhydride with the chemical formula CFS3O. It is a colorless liquid with a sharp odor, known for its extreme reactivity and ability to act as a powerful electrophilic reagent. This compound is highly corrosive and can cause severe burns upon contact with skin or eyes.

What are the main uses of Trifluoromethanesulfonic Anhydride (CAS: 358-23-6)?

Trifluoromethanesulfonic Anhydride is widely used in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It serves as a key reagent in fluorination reactions and is employed in the production of fluoroorganic compounds. Its applications also extend to research and industrial processes where strong sulfonic acid derivatives are required.

Is Trifluoromethanesulfonic Anhydride (CAS: 358-23-6) safe?

Trifluoromethanesulfonic Anhydride is not considered safe for handling without proper precautions. It is toxic and can cause serious health effects, including respiratory irritation and skin burns. Protective equipment such as gloves, goggles, and a fume hood is essential. Safety standards emphasize avoiding inhalation and contact with the skin or eyes.

How should Trifluoromethanesulfonic Anhydride (CAS: 358-23-6) be stored?

Trifluoromethanesulfonic Anhydride should be stored in a tightly sealed container in a cool, dry, and well-ventilated area. It is hygroscopic and reactive to moisture, so it must be kept away from humidity and light. Storage should be in a place that is not accessible to children and in compliance with local hazardous material regulations.
