Used as an ionic liquid in electrochemical applications such as lithium-ion batteries and supercapacitors due to its high ionic conductivity and wide electrochemical stability window. Its thermal stability and low volatility make it suitable for high-temperature processes. Commonly employed as a solvent in organic synthesis and catalysis where non-volatile, polar media are required. Also investigated in carbon dioxide capture and separation technologies owing to its gas solubility properties. Applied in analytical chemistry as a matrix or additive in mass spectrometry to improve ionization efficiency.
