Common Name | 2-Methyl-2-pentenal |
---|
Description | 2-Methyl-2-pentenal belongs to the class of organic compounds known as enals. These are an alpha,beta-unsaturated aldehyde of general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 2-Methyl-2-pentenal is a fruity, gassy, and green tasting compound. 2-Methyl-2-pentenal is found, on average, in the highest concentration within safflowers (Carthamus tinctorius). 2-Methyl-2-pentenal has also been detected, but not quantified in, several different foods, such as green tea, garden onions (Allium cepa), nuts, garden onion (var.), and robusta coffees (Coffea canephora). This could make 2-methyl-2-pentenal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-2-pentenal. |
