Metabolite Identification
Common NameMethylhalfordinol
DescriptionMethylhalfordinol belongs to the class of organic compounds known as phenyl-1,3-oxazoles. These are aromatic heterocyclic compounds containing a 1,3-oxazole substituted at one or more positions by a phenyl group. Methylhalfordinol has been detected, but not quantified in, fruits. This could make methylhalfordinol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Methylhalfordinol.
