Platinum compounds are chemical substances that contain the element platinum. They are often used in various applications, including catalysis, medicine, and electronics. These compounds can exist in different forms, such as salts, complexes, and organometallics, and they exhibit unique properties due to the presence of platinum. In medicine, certain platinum compounds, like cisplatin, are used as chemotherapy agents to treat various types of cancer. Their ability to bind to DNA helps inhibit cancer cell growth. Additionally, platinum compounds play a crucial role in industrial processes, serving as catalysts to speed up chemical reactions.
