Used as a titrant in non-aqueous acid-base titrations for the determination of weak organic acids, particularly in pharmaceutical analysis. Commonly applied in the quality control of drugs such as barbiturates, sulfonamides, and other acidic active pharmaceutical ingredients. Also employed in the standardization of perchloric acid solutions and in potentiometric titrations where a strong organic base is required. Its role as a reference base ensures accurate and reproducible results in analytical procedures involving organic matrices.
