Dihydrogen dioxide is literally H2O2. This is better known as hydrogen peroxide 3%) [affil links]. Now tell me what dihydrogen oxide is!

It sounds to me like you are looking for something with the chemical formula H2O2. This is often used in teeth whitening systems and also in industrial applications. But to answer your question directly, go to your medicine cabinet and look for a bottle of hydrogen peroxide. Now you've found H2O2.
