PRODUCT USAGE

Tetrabutylammonium Perchlorate (TBAP for short), with CAS No. 2537-36-2 and chemical formula C₁₆H₃₆ClNO₄, appears as white crystalline powder, easily soluble in organic solvents such as acetonitrile and methanol, and is a commonly used quaternary ammonium salt electrolyte. Its core application is in the electrochemical field. As a supporting electrolyte for non-aqueous electrolytes, it is widely used in lithium-ion batteries, supercapacitors, electrochemical synthesis and electrochemical analysis, which can improve the conductivity and stability of electrolytes and ensure the efficient operation of electrochemical systems. In the field of organic synthesis, it is used as a phase transfer catalyst to accelerate the reaction between aqueous and organic phases, improve reaction rate and yield, and is often used in nucleophilic substitution, redox and other reactions. In addition, it is used in the field of chemical analysis as an ion-pair reagent to assist chromatographic separation, and is also an important intermediate in organic synthesis, serving as an indispensable special chemical raw material in electrochemical and fine chemical fields.
