Used in titration analysis to determine the concentration of acidic substances in non-aqueous environments. Ideal for analyzing weak acids that do not dissolve well in water, such as organic acids in pharmaceuticals, fats, and oils. Commonly applied in quality control of industrial chemicals, food products, and drug formulations. Also used in saponification value testing for fats and oils in the production of soaps and biodiesel. Stable and accurate for volumetric analysis when calibrated properly.
