Used as a reference standard in quality control processes to ensure accurate testing and analysis of potassium bromate in industrial and food safety laboratories. It helps calibrate instruments and validate analytical methods, particularly in monitoring bromate levels in flour and baked goods, where it may be present as a flour improver. Ensures compliance with regulatory limits due to its potential health risks when present in high concentrations. Also used in the verification of test kits and chromatographic techniques for reliable detection and quantification.
