Description

Copper(II) Bis(trifluoromethanesulfonyl)imide (CAS No. 162715-14-2) is a high-purity inorganic salt widely used in electrochemical and catalytic applications due to its exceptional stability and conductivity properties. With the molecular formula C₄CuF₁₂N₂O₈S₄, this compound features a copper(II) cation paired with two trifluoromethanesulfonylimide (TFSI) anions, offering excellent solubility in polar organic solvents and ionic liquids. Ideal for advanced research, this 99.5% pure reagent is essential for lithium-ion battery electrolytes, supercapacitors, and as a Lewis acid catalyst in organic synthesis. Its moisture-sensitive nature necessitates storage under inert conditions to maintain performance integrity.
