Used as a precursor in the synthesis of pyridinium-based ionic liquids, which serve as catalysts and solvents in organic reactions due to their low volatility and high thermal stability. Also applied in electrochemical systems, such as in electrolytes for batteries and supercapacitors, where it helps improve conductivity and charge transfer. Its bromide salt form supports phase-transfer catalysis, enabling efficient anion exchange in industrial processes. Additionally, it is investigated for use in corrosion inhibitors and surface treatments for metals, offering protection in aggressive environments.
