Chemical Information
FooDB Name2-Acetyl-4,5-dihydrothiazole
Description2-Acetyl-4,5-dihydrothiazole belongs to the class of organic compounds known as thiazolines. These are heterocyclic compounds containing a five-member unsaturated aliphatic ring with one nitrogen atom, one sulfur atom, three carbon atoms. 2-Acetyl-4,5-dihydrothiazole is a bread, chip, and corn tasting compound. 2-Acetyl-4,5-dihydrothiazole has been detected, but not quantified in, alcoholic beverages and corns (Zea mays). This could make 2-acetyl-4,5-dihydrothiazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Acetyl-4,5-dihydrothiazole.
