Metabolite Identification
Common NameEtiroxate
DescriptionEtiroxate, also known as etiroxic acid or skleronorm, belongs to the class of organic compounds known as diphenylethers. These are aromatic compounds containing two benzene rings linked to each other through an ether group. Based on a literature review a significant number of articles have been published on Etiroxate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Etiroxate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Etiroxate 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.
