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\u2032-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.
