The Platinum Compound Behind Modern Catalysis, Coatings & Clean Energy
Chloroplatinic acid (H₂PtCl₆) is the primary industrial gateway to platinum — a highly soluble, readily convertible salt that serves as the starting point for catalyst manufacturing, nanoparticle synthesis, electroplating, platinum refining, and analytical chemistry. At purities from 99.9% to 99.9995%, Pure Laboratories manufactures CPA to meet the most demanding specifications across research and production.
Why Purity Defines Performance in Platinum Chemistry
Chloroplatinic acid is only as valuable as it is pure. In hydrosilylation catalysis, trace contaminants disrupt reaction selectivity and shorten catalyst service life. In nanoparticle synthesis, impurities alter particle morphology in ways that cannot be corrected downstream. In analytical applications, parts-per-billion-level contamination compromises quantitative results. And in platinum refining and electroplating baths, inconsistent feedstock creates inconsistent output.
The compound's core advantages — high water solubility, excellent platinum bioavailability for chemical processing, and ease of conversion to metallic platinum or nanoscale particles — are only fully realized when the material is rigorously characterized and certified. Every lot of CPA from Pure Laboratories is backed by a comprehensive Certificate of Analysis, verified in-house or through independent third-party laboratories.
The Advantages of Chloroplatinic Acid
Chloroplatinic acid has remained the platinum compound of choice across industries for decades — not by accident, but because its chemical properties make it uniquely suited to demanding applications. Where other platinum sources fall short in solubility, processability, or versatility, CPA delivers.
High Water Solubility Unlike many platinum compounds, CPA dissolves readily in water and a wide range of polar solvents. This makes it ideal for homogeneous catalyst systems, wet chemical processing, and electroplating baths where uniform distribution of platinum is critical to consistent results.
Readily Convertible to Metallic Platinum CPA can be reduced to high-purity metallic platinum through straightforward chemical or electrochemical methods — giving manufacturers precise control over the form, particle size, and morphology of the final platinum material. This flexibility is what makes it the preferred feedstock for nanoparticle synthesis and electrocatalyst production.
Exceptional Platinum Availability As a fully dissolved platinum salt, CPA delivers platinum in a chemically active, immediately accessible form. There is no need for aggressive dissolution steps or elevated temperatures — the platinum is ready to react, plate, or precipitate from the moment it enters your process.
Broad Process Compatibility From hydrosilylation baths to refining circuits to analytical reagent workflows, CPA integrates cleanly into established industrial and laboratory chemistries without requiring significant process modifications.
Scalable from Lab to Production Whether you're running small-scale research syntheses or high-volume catalyst manufacturing, CPA is available in quantities and purity grades that scale with your needs — making it a reliable choice at every stage of development and production.
