Used as a reference standard in analytical laboratories for the accurate determination of boric acid content in various samples. Commonly applied in quality control and calibration procedures for techniques such as titration, spectrophotometry, and ion chromatography. Ensures consistency and reliability in environmental testing, pharmaceutical analysis, and industrial process monitoring where precise measurement of boron compounds is required. Also utilized in the preparation of buffer solutions and in the validation of testing methods for water, cosmetics, and disinfectants.
