Key Properties
Tetramethylammonium hydroxide 0.1N solution in 2-propanol is a standardized preparation for non-aqueous titration applications. This solution is particularly useful in analytical chemistry for titrating weak acids and bases, providing a reliable means of determining concentrations in non-aqueous environments. The tetramethylammonium ion acts as a strong base, making it suitable for various titrations where water is not the solvent of choice. Its formulation in 2-propanol enhances its solubility and stability, making it a preferred choice for laboratory settings.
Also known as Tetramethylammonium hydroxide solution.
