Used as an anion stabilizer and phase-transfer catalyst in organic synthesis, particularly in reactions requiring non-coordinating anions. It is effective in polymerization processes, such as in the production of polyolefins, where it helps stabilize active catalyst sites. Also employed in electrochemical applications, including battery research and conductive materials, due to its ability to enhance ionic conductivity. Its lipophilic nature makes it suitable for use in membrane technologies and sensors, where ion transport and selectivity are critical.
