Butanedione, also known as diacetyl, is a colorless organic compound with a buttery flavor and aroma. It is commonly used in the food industry as a flavoring agent, particularly in popcorn and dairy products. Butanedione has the chemical formula C4H6O2 and is classified as a diketone due to the presence of two carbonyl groups. In addition to its use in food, butanedione is also utilized in various industrial applications, including the production of certain plastics and as a solvent. However, exposure to high levels of butanedione can pose health risks, leading to concerns about its safety in occupational settings.
