Metabolite Identification
Common Name2-Butyl-5-methyl-4-propyloxazole
Description2-Butyl-5-methyl-4-propyloxazole 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-Butyl-5-methyl-4-propyloxazole has been detected, but not quantified in, potatos (Solanum tuberosum). This could make 2-butyl-5-methyl-4-propyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Butyl-5-methyl-4-propyloxazole.
