Chemical Information
FooDB Name2-Isobutyl-4,5-dimethyloxazole
Description2-Isobutyl-4,5-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. 2-Isobutyl-4,5-dimethyloxazole is a burnt and roasted tasting compound. 2-Isobutyl-4,5-dimethyloxazole has been detected, but not quantified in, potatos (Solanum tuberosum). This could make 2-isobutyl-4,5-dimethyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Isobutyl-4,5-dimethyloxazole.
