Used in analytical chemistry for the determination of reducing agents through iodometric titrations. Commonly applied in the quantification of sulfites, thiosulfates, and ascorbic acid in food and pharmaceutical samples. Also employed in the standardization of sodium thiosulfate solutions. Suitable for use in redox titrations where a stable and precise oxidizing agent is required. Widely utilized in quality control laboratories for water analysis, including the measurement of oxygen demand and disinfectant levels.
