Used as a specialty solvent and catalyst in organic synthesis, particularly in reactions requiring mild acidic conditions. Its unique structure allows for effective proton transfer while maintaining stability, making it suitable for use in peptide coupling and heterocycle formation. Also employed in electrochemical applications due to its ionic character and ability to enhance conductivity in non-aqueous systems. Additionally, it finds use in the formulation of certain pharmaceutical intermediates where controlled reactivity and solubility are required.
