Used as an ionic liquid precursor in electrochemical applications, particularly in the development of sensors and conductive materials. Its stable cationic structure makes it suitable for use in electrolytes for batteries and supercapacitors. Also employed in organic synthesis as a phase-transfer catalyst, enhancing reaction efficiency in biphasic systems. Additionally, it finds use in the study of antimicrobial agents due to the bioactivity associated with pyridinium-based compounds.
