Description

Antimony Pentafluoride (SbF5) is a highly reactive inorganic compound with the molecular formula F5Sb. This colorless, viscous liquid is one of the strongest Lewis acids known, making it an invaluable reagent in advanced chemical synthesis and catalysis. With a CAS number of 7783-70-2, it is widely recognized for its role in superacid systems, particularly when combined with fluorosulfuric acid (HSO3F) to form the legendary Magic Acid. Antimony pentafluoride is hygroscopic and must be handled under strict anhydrous conditions. Ideal for researchers and industrial chemists, it is available in high-purity grades suitable for fluorination reactions, polymer chemistry, and electrochemical applications. Proper storage in sealed containers under inert gas is essential to maintain its reactivity and shelf life.

Application

Antimony pentafluoride is primarily used as a potent fluorinating agent and catalyst in organic and inorganic synthesis. It plays a critical role in the production of superacids for carbocation studies and hydrocarbon activation. In industrial settings, it is employed in the manufacture of specialty fluorochemicals and as a component in certain fluoride glass formulations. Its extreme Lewis acidity also makes it useful in polymerization reactions and as a catalyst in isomerization processes.
