Metabolite Identification
Common NameSudan III
DescriptionSudan III, also known as c.i. 26100 or solvent red 23, belongs to the class of organic compounds known as azobenzenes. These are organonitrogen aromatic compounds that contain a central azo group, where each nitrogen atom is conjugated to a benzene ring. Based on a literature review a significant number of articles have been published on Sudan III. This compound has been identified in human blood as reported by (PMID: 31557052 ). Sudan iii is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Sudan III 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.
