  • Applications

    Stannous Chloride, CAS 7772-99-8, is widely used across industries as a reducing agent and as a chemical intermediate. In textiles and printing, it acts as a mordant/fixer to help dyes bond to fibers. In photography and historical chemical processes, it has historically served as a reducing agent in silver halide processes and toning formulations. In metal finishing and electronics, it provides tin(II) ions in plating baths and facilitates metal deposition in electroplating. In analytical chemistry, it is used as a laboratory reducing agent and reagent for various colorimetric and speciation tests.
