Metabolite Identification

Common Name

5-Butyloxazole

Description

5-Butyloxazole belongs to the class of organic compounds known as oxazoles. Oxazoles are compounds containing an oxazole ring, which is a five-membered aromatic heterocycle with one oxygen, one nitrogen, and three carbon atoms. Isomers include 1,2-oxazole and 1,3-oxazole. 5-Butyloxazole has been detected, but not quantified in, nuts. This could make 5-butyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Butyloxazole.
