Hexachloroplatinic Acid / Chloroplatinic Acid — CAS 16941-12-1

Chloroplatinic Acid, CAS 16941-12-1, also known as Hexachloroplatinic Acid or Hydrogen Hexachloroplatinate(IV), is an inorganic platinum compound used as a platinum precursor in catalyst manufacturing, platinum-based materials, chemical synthesis, nanomaterial production and specialized metal-processing applications. Commercial products are supplied in different forms and concentrations, including aqueous solutions, so the exact form and platinum content should be confirmed by the product specification and CoA.

Key Applications

Chloroplatinic acid is used as a platinum precursor for catalyst preparation, including platinum nanoparticles and supported platinum catalysts, and is also used in specialized electrochemical and chemical-processing applications.

Storage & Handling

Chloroplatinic acid is hygroscopic and requires controlled handling. Supplier safety information identifies significant corrosive, acute-toxicity and sensitization hazards; storage, PPE, transport and handling should always follow the current SDS for the specific grade and concentration.

Important Specification Note

For this product, do not publish a fixed “99%” purity or fixed platinum percentage as UAB's specification unless your actual supplier CoA confirms it. Commercial references show substantially different forms—for example, an 8 wt.% aqueous solution, while other chloroplatinic acid products are specified by platinum content.
