Platinum tetrachloride is commonly used as a catalyst precursor, especially in organic synthesis reactions. It can promote the addition, hydrogenation and isomerization of olefin. As a common platinum compound, platinum tetrachloride is widely used as a raw material for the synthesis of other platinum compounds, such as platinum complexes, platinum nanoparticles, etc. It can be used to prepare metal platinum films, conductive coatings and electrode materials, which are widely used in electronic devices, optoelectronics and semiconductor industries. Platinum tetrachloride can be used as the precursor of palladium synthesis catalyst for organic synthesis, oxidation, reduction and other reactions. Platinum can be also used in pharmaceutical field: drugs are an important class of anti-tumor drugs, platinum tetrachloride is one of the important intermediates, used for the preparation of platinum anti-tumor drugs, such as Cisplatin and Carboplatin.
