Common Name | 4-Methyl-2,3-pentanedione |
---|
Description | 4-Methyl-2,3-pentanedione belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. 4-Methyl-2,3-pentanedione is a sweet, buttery, and creamy tasting compound. 4-Methyl-2,3-pentanedione has been detected, but not quantified in, several different foods, such as robusta coffees (Coffea canephora), coffee and coffee products, alcoholic beverages, crustaceans, and arabica coffees (Coffea arabica). This could make 4-methyl-2,3-pentanedione a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4-Methyl-2,3-pentanedione. |
