Chemical Information
FooDB NamePyrrol-2-methylketone
Description2-acetylpyrrole, also known as 1-(1h-pyrrol-2-yl)1-ethanone or 2-pyrrolyl methyl ketone, is a member of the class of compounds known as aryl alkyl ketones. Aryl alkyl ketones are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. 2-acetylpyrrole is soluble (in water) and a very weakly acidic compound (based on its pKa). 2-acetylpyrrole is a bread, coumarin, and licorice tasting compound and can be found in a number of food items such as green vegetables, tea, nuts, and white mustard, which makes 2-acetylpyrrole a potential biomarker for the consumption of these food products.
