Used as a titrant in non-aqueous titrations, particularly for the determination of weak acids in organic solvents. It is especially valuable in the analysis of acidic pharmaceutical compounds, fatty acids, and other organic substances that do not dissolve well in water. Its strong basicity and solubility in organic media make it ideal for potentiometric titrations where precise endpoint detection is required. Commonly employed in quality control and analytical laboratories for standardizing solutions and assaying active ingredients in drug formulations.
