Product Details

Products Description of Selenium dioxide

Selenium dioxide is mainly defined as an oxidizing reagent in organic synthesis, and it is involved in a number of oxidation reactions. Probably due to the toxicity of this reagent, many of these reactions have been gradually replaced in recent years by other, better reagents from Chemicalbook. However, the oxidation reactions of selenium dioxide with reactive methyl, methylene, and hypomethyl groups still play an important role in organic chemical functional group conversions.
