Metabolite Identification
Common NameFenhexamid
DescriptionFenhexamid, also known as KBR 2738 or teldor, belongs to the class of organic compounds known as anilides. These are organic heterocyclic compounds derived from oxoacids RkE(=O)l(OH)m (l not 0) by replacing an OH group by the NHPh group or derivative formed by ring substitution. Based on a literature review a significant number of articles have been published on Fenhexamid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Fenhexamid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Fenhexamid 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.
