Application


  • Hydration structures of lactic acid: Research explored the hydration structures of lactic acid and characterized the ionic clathrate hydrate formed with a biological organic acid anion, utilizing Tetra-n-butylammonium hydroxide in this process (Muromachi et al., 2014).

  • Protection of ribonucleosides in RNA synthesis: A study demonstrated the use of Tetra-n-butylammonium hydroxide in the solid-phase synthesis of RNA sequences, particularly for the protection of 2′-hydroxyl groups of ribonucleosides (Cieslak et al., 2013).

  • Analysis of cosmetic products: Tetra-n-butylammonium hydroxide is used as a ion-pairing agent in the simultaneous analysis of various organic acids in cosmetic products by enhancing the extraction efficiency during high-performance liquid chromatography (Mikami et al., 2002).

  • Determination of calcium dobesilate in human plasma: The compound was employed in the ion-pairing extraction and high-performance liquid chromatography for the determination of calcium dobesilate in human plasma, highlighting its utility in clinical analytical methods (Rona and Ary, 2001).
