Chloroplatinic acid solution CAS 16941-12-1

High-Purity Chloroplatinic Acid Solution from Aure Chemical – Your Trusted Source

Chloroplatinic acid solution, also known as hexachloroplatinic(IV) acid or dihydrogen hexachloroplatinate(IV) solution, CAS No. 16941-12-1, is a critical aqueous platinum(IV) source widely used in precious metal applications. Supplied by Aure Chemical as a clear to reddish-orange liquid with platinum concentrations typically ranging from 8–25% Pt (w/w), this stable solution offers high platinum solubility and serves as an efficient precursor for preparing hydrosilylation catalysts, supported heterogeneous catalysts, electroplating baths, and various platinum compounds. Its convenience in liquid form reduces handling risks compared to solids while maintaining excellent reactivity and purity for catalyst manufacturing, silicone curing systems, surface coatings, and inorganic syntheses in catalysis, electronics, and fine chemicals. Aure Chemical provides precise Pt content control, low impurity profiles, and secure supply to ensure reproducible results in industrial and R&D processes.
