Potassium Sulphate K2SO4 AR 500g

Potassium Sulphate K2SO4 AR 500g It is used in the laboratory for analysis and research purposes Potassium sulfate may be used as a sulfonating agent in the preparation of 4′-dibenzo-18-crown-6-sulfonic acid via sulfonation of dibenzo-18-crown-6. Potassium sulfate may be used in the preparation of needlelike mullite particles. It may be used as a buffer for minimizing the adsorption of proteins on fused-silica capillaries in capillary zone electrophoresis Grade AR reagent Assay ≥99.0% Form powder Impurities ≤0.01% insolubles ≤5 ppm N compounds pH 5.5-5.8 (25 °C, 5%) anion traces chloride (Cl–): ≤0.001% cation traces Ca: ≤0.01% Fe: ≤5 ppm Mg: ≤0.005% Na: ≤0.02% heavy metals (as Pb): ≤5 ppm SMILES string [K+].[K+].[O-]S([O-])(=O)=O
