Chempedia is a free service for uniquely identifying and naming chemical substances. If you or your organization work with chemical substances and would like a convenient way to keep track of them in spreadsheets, wikis, web pages and other databases, Chempedia can help. If you just have a substance name, you can use Chempedia to find what's known about it.
