Key Properties
Tetrakis(decyl)ammonium bromide (AR/HPLC) is a bulky, lipophilic ion-pairing reagent that plays a crucial role in enhancing the separation of analytes in high-performance liquid chromatography (HPLC). This compound is particularly useful in reversed-phase HPLC applications, where it aids in the retention and separation of polar compounds by forming ion pairs with them. Its unique structure, featuring four decyl groups, contributes to its lipophilicity, making it effective in various organic solvent systems. The high purity level of 99% ensures reliable performance in analytical applications, making it suitable for research and industrial use.
Also known as Tetradecyltrimethylammonium bromide.

- Substance
Tetrakis(decyl)ammonium bromide appears as a white to off-white waxy solid. It has a melting point of approximately 60-70 °C and is soluble in a variety of organic solvents, including methanol, ethanol, and acetone, but is insoluble in water. The compound has a density of around 0.9 g/cm³, which is typical for lipophilic quaternary ammonium salts. Its high molecular weight of 659.01 g/mol reflects its complex structure, and it exhibits a characteristic odor that is mild and not overpowering.
