Metabolite Identification

Common Name

2-Methyl-5-propyloxazole

Description

2-Methyl-5-propyloxazole belongs to the class of organic compounds known as 2,5-disubstituted oxazoles. 2,5-disubstituted oxazoles are compounds containing an oxazole ring substituted at positions 2 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-Methyl-5-propyloxazole has been detected, but not quantified in, nuts. This could make 2-methyl-5-propyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-5-propyloxazole.
