Metabolite Identification
Common Name5-Isoxazoleacetic acid, 4,5-dihydro-3-(4-hydroxyphenyl)-, methyl ester
Description5-Isoxazoleacetic acid, 4,5-dihydro-3-(4-hydroxyphenyl)-, methyl ester belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position. Based on a literature review very few articles have been published on 5-Isoxazoleacetic acid, 4,5-dihydro-3-(4-hydroxyphenyl)-, methyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-isoxazoleacetic acid, 4,5-dihydro-3-(4-hydroxyphenyl)-, methyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-Isoxazoleacetic acid, 4,5-dihydro-3-(4-hydroxyphenyl)-, methyl ester is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
