Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. It is particularly effective in nucleophilic substitution reactions and polymerization processes. Also employed in electrochemical applications, such as in electrolytes for batteries (including lithium-ion) and supercapacitors, due to its ionic conductivity and stability. Additionally, it serves as a stabilizer in the production of specialty chemicals and polymers, enhancing their performance and durability. Furthermore, it is utilized in separation and extraction processes owing to its specific solubility properties.
