Hexachloroplatinic acid hexahydrate is a platinum-based coordination compound, primarily used as a precursor in the synthesis of platinum catalysts, plating solutions, and as a reagent in analytical chemistry for determining potassium and ammonium, which it precipitates as insoluble hexachloroplatinate salts such as K2PtCl6. It is a red-brown crystalline solid with high solubility in water. This chemical has the CAS number 18497-13-7, with the molecular formula H₂PtCl₆·6H₂O and a molecular weight of 517.90 g/mol. It requires careful handling due to its hazardous nature, indicated by the signal word "Danger," and should be stored at ambient conditions. Molekula supplies hexachloroplatinic acid hexahydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
