CAS 20039-37-6: Dipyridinium dichromate
Description:Dipyridinium dichromate is an inorganic compound characterized by its bright orange-red color and is often used as a strong oxidizing agent in organic synthesis. It consists of two pyridine rings (hence the name "dipyridinium") and dichromate ions, which are derived from chromium. The compound is typically encountered as a crystalline solid and is soluble in water, releasing chromate ions in solution. Dipyridinium dichromate is known for its ability to oxidize a variety of organic substrates, making it valuable in synthetic chemistry, particularly in the oxidation of alcohols to carbonyl compounds. However, it is important to handle this substance with care, as it is toxic and poses environmental hazards due to the presence of hexavalent chromium, which is a known carcinogen. Proper safety precautions, including the use of personal protective equipment and adherence to waste disposal regulations, are essential when working with this compound.
