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 moderately basic compound (based on its pKa). 4-Ethyl-2,5-dimethyloxazole is a burnt and roasted tasting compound. 4-Ethyl-2,5-dimethyloxazole has been detected, but not quantified in, coffee and coffee products and potato. This could make 4-ethyl-2,5-dimethyloxazole a potential biomarker for the consumption of these foods.
