Used as a phase-transfer catalyst in organic synthesis, enabling reactions between compounds in different phases by transferring ions into organic solvents. Commonly applied in nucleophilic substitutions, alkylations, oxidations, and esterifications where strong basic conditions are needed. Also employed in the preparation of nanoparticles due to its ability to stabilize and control particle growth in non-aqueous media. Additionally, used as a base for deprotonation of weakly acidic organic compounds, such as phenols or β-diketones. Its long alkyl chains provide solubility in organic solvents, making it effective in industrial and laboratory-scale reactions requiring mild and soluble base systems, including pharmaceutical and specialty chemical production.
