The GB/T 649-2023 standard specifies the properties, technical requirements, test methods, inspection rules, and Encasement and labeling requirements of the chemical reagent potassium bromide. The molecular formula of potassium bromide is KBr, the relative molecular mass is 119.00 (according to the 2022 International Relative Atomic Mass), and the CAS number is 7758-02-3. This standard applies to the inspection of the chemical reagent potassium bromide to ensure that it meets the requirements for quality control and safe use. A series of relevant documents are cited in the standard, including the preparation of preparation products, the determination of impurities, the determination of pH value of reagents, and the general method for the determination of heavy metals, water insoluble substances, iron and other elements. The application of these cited documents ensures the comprehensive control and accurate detection of the mass of potassium bromide reagents.
