Dicarbonyl compounds are organic molecules that contain two carbonyl groups, which are functional groups characterized by a carbon atom double-bonded to an oxygen atom (C=O). These compounds can be found in various forms, including aldehydes and ketones, and are important in organic chemistry due to their reactivity and role in synthesis. Common examples of dicarbonyl compounds include glyoxal and malondialdehyde. They are often used in the production of polymers, pharmaceuticals, and fragrances. The presence of two carbonyl groups can significantly influence the chemical properties and reactivity of these compounds, making them valuable in various chemical reactions.
