Sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (Cat No.:R073943) is a white to off-white crystalline salt composed of a sodium cation and a large, weakly coordinating borate anion bearing four highly fluorinated aryl groups. It is widely used in organometallic and coordination chemistry as a non-coordinating counterion, enabling high reactivity and stability of cationic metal complexes. Its bulk and electron-withdrawing trifluoromethyl groups reduce nucleophilicity, making it ideal for catalysis and ionic-liquid research. Moisture-sensitive, it should be stored in a dry, inert atmosphere and handled with appropriate laboratory safety measures.
