What Is Potassium tetrakis(perfluorophenyl)borate?
Potassium tetrakis(perfluorophenyl)borate (CAS 89171-23-3), commonly also called potassium tetrakis(pentafluorophenyl)borate, is the potassium salt of the tetrakis(pentafluorophenyl)borate anion [B(C6F5)4]−. Molecular formula C24BF20K; molecular weight about 718.14 g/mol. Always match CAS 89171-23-3 on the batch COA.
The bulky, electron-withdrawing perfluorophenyl framework makes [B(C6F5)4]− a widely used weakly coordinating anion in coordination chemistry and catalyst activation work. Monuo Chemical supplies this material as a specialty chemical raw material under Custom synthesis, with batch identity documentation (COA / SDS). Finished-product claims, labeling and local regulatory filings remain the brand manufacturer’s responsibility. Confirm grade and assay against the batch COA for your intended method.
