Used in analytical chemistry for the determination of certain substances through titration methods, particularly in the analysis of phenols and other organic compounds. It serves as a reliable oxidizing agent in redox titrations due to its consistent reactivity and stability in solution. Commonly applied in quality control laboratories for calibration and standardization of titrants. Also utilized in the validation of analytical methods where precise and accurate concentration measurements are required. Its role as a standard solution ensures reproducibility and traceability in chemical assays.
