    Stannous Chloride Dihydrate CAS 10025-69-1

    Stannous Chloride Dihydrate, defined by CAS 10025-69-1, is a white crystalline inorganic salt that functions as a potent reducing agent and a primary source of divalent tin in electrochemical and chemical synthesis environments. Known technically as Tin(II) chloride dihydrate, this compound operates through its high affinity for oxygen, making it an essential sensitizing agent for glass metallization and plastic plating processes. In large-scale textile manufacturing, this Tin protochloride derivative acts as a mordant for dyeing operations and a discharge agent in printing, while in organic chemistry, Stannous dichloride dihydrate is utilized in the Stephen reduction for the synthesis of aldehydes from nitriles. As a versatile Tin dichloride crystal, it is also integrated into pharmaceutical intermediates and specialized electroplating baths to ensure uniform metal deposition. We facilitate bulk supply for industrial synthesis lines and surface treatment facilities, providing customized specifications regarding purity levels and acidity to suit specific reaction kinetics. Our distribution model ensures competitive factory pricing for international procurement, with every shipment meticulously supported by updated MSDS, TDS, COA documentation.

    Applications

    • Electroplating & Surface Treatment: Used as a sensitizer for silvering mirrors and as an electrolyte component in tin-plating baths for steel and electronic components.
    • Chemical Synthesis: Acts as a catalyst in organic reactions, specifically as a reducing agent for nitro groups and nitriles.
    • Textile Industry: Employed as a mordant in the dyeing of cochineal on wool and as a bleaching agent in specialized fabric treatments.

    Storage & Quality Assurance

    Stannous Chloride Dihydrate must be stored in tightly sealed, acid-resistant containers in a cool, dry warehouse. Our facility implements a double-titration method to verify the precise Sn2+ content, ensuring minimal oxidation. Each lot undergoes comprehensive performance testing in simulated neutral conditions to ensure the material meets international industrial benchmarks.

    FAQ - Technical & Supply Chain

    • Q:

      How is the valence stability of this Stannous Chloride Dihydrate verified?

      A: The identity of CAS 10025-69-1 is confirmed through periodic iodometric titration, which specifically quantifies the divalent tin (Sn2+) concentration, ensuring no oxidation to the inactive Sn4+ state.
    • Q:

      Is this Tin(II) chloride dihydrate suitable for use in highly acidic electroplating baths?

      A: Yes, it is intended for use as a primary tin source in acidic plating formulations where high ionic conductivity and rapid metal deposition are required.
    • Q:

      Why does the solution turn cloudy when dissolved in water, and how can it be resolved?

      A: This is a natural chemical characteristic of stannous chloride due to hydrolysis, which forms insoluble basic salts. To achieve a perfectly clear solution for electroplating or sensitizing, it must be dissolved in a heavily acidic medium. We recommend dissolving the crystals in concentrated hydrochloric acid (HCl) first, before carefully diluting with water to the desired concentration.
