CAS 358-23-6: Trifluoromethanesulfonic anhydride

Description: Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is a highly reactive chemical compound characterized by its strong electrophilic properties. It is a colorless to pale yellow liquid at room temperature and has a pungent odor. The compound is known for its ability to act as a powerful sulfonating agent, making it useful in various organic synthesis reactions, particularly in the preparation of sulfonic acids and esters. Its molecular structure features a trifluoromethyl group attached to a sulfonic anhydride moiety, which contributes to its high reactivity and stability under certain conditions. Trifluoromethanesulfonic anhydride is soluble in polar organic solvents but reacts vigorously with water, releasing triflic acid, a strong acid. Due to its corrosive nature, it requires careful handling and storage in inert atmospheres to prevent hydrolysis. Its applications extend to the pharmaceutical industry, materials science, and as a catalyst in various chemical reactions. Safety precautions are essential when working with this compound due to its toxic and corrosive properties.
