Chemical Information
FooDB Name2-Acetylthiophene
Description2-Acetylthiophene belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. 2-Acetylthiophene is a sulfury tasting compound. 2-Acetylthiophene is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes). 2-Acetylthiophene has also been detected, but not quantified in, asparagus (Asparagus officinalis). This could make 2-acetylthiophene a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Acetylthiophene.
