Metabolite Identification
Common NamePendimethalin
DescriptionPendimethalin, also known as penoxalin, belongs to the class of organic compounds known as dinitroanilines. These are organic compounds containing an aniline moiety, which is substituted at 2 positions by a nitro group. Based on a literature review a significant number of articles have been published on Pendimethalin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pendimethalin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pendimethalin 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.
