Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. It is also employed in the preparation of silica-based materials and in the synthesis of nanoparticles. Additionally, it serves as a titrant in non-aqueous titrations for determining acidic compounds. In the electronics industry, it is used in the development of liquid crystal displays and as an etchant in the manufacturing of semiconductors. Its role in analytical chemistry includes acting as an ion-pairing agent in chromatography to improve separation efficiency.
