This chemical is primarily used as a biocide in antifouling paints for marine vessels. It prevents the growth of organisms like barnacles, algae, and mollusks on ship hulls, improving fuel efficiency and reducing maintenance costs. Additionally, it has applications in wood preservation, protecting against fungal decay and insect damage in treated lumber. Its effectiveness in controlling harmful organisms makes it valuable in industrial and marine settings, though its environmental impact has led to stricter regulations and reduced usage in recent years.
