Chemical Information
FooDB Name4-Ethyl-2,5-dimethyloxazole
Description4-Ethyl-2,5-dimethyloxazole belongs to the class of organic compounds known as 2,4,5-trisubstituted oxazoles. 2,4,5-trisubstituted oxazoles are compounds containing an oxazole ring substituted at positions 2, 4 and 5 only. Oxazole is a five-membered aromatic heterocycle with one oxygen, one nitrogen, and three carbon atoms. Isomers include 1,2-oxazole and 1,3-oxazole. 4-Ethyl-2,5-dimethyloxazole is a burnt and roasted tasting compound. 4-Ethyl-2,5-dimethyloxazole has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, potatos (Solanum tuberosum), and robusta coffees (Coffea canephora). This could make 4-ethyl-2,5-dimethyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4-Ethyl-2,5-dimethyloxazole.
