Strontium chloride hexahydrate is a precursor to prepare strontium chromate which is used as a corrosion inhibitor for aluminum. It is involved in the synthesis of cadmium sulfide core photocatalytic nanoparticles. It is used as a red coloring agent in pyrotechnics. Furthermore, it is utilized in glass-making and metallurgy. In the medical field, its radioactive isotope strontium-89 is used for the treatment of bone cancer. It acts as a catalyst in the conversion of ketones and aldehydes to the corresponding gem-dihydroperoxides using aqueous hydrogen peroxide.
