Ammonium chloroplatinate (NH₄)₂[PtCl₆]（Cat No.:M087460）is an orange-red crystalline salt composed of ammonium cations and a hexachloroplatinate(IV) anion. It is a key intermediate in platinum refining and recovery processes. The compound is sparingly soluble in cold water and decomposes upon heating, releasing platinum metal. Ammonium chloroplatinate is commonly used in the preparation of other platinum compounds, as a precursor for catalyst production, and in analytical chemistry for platinum detection. Due to its ability to release elemental platinum upon reduction, it plays an important role in metallurgy and materials science.
