Metabolite Identification
Common Name1,3-Dimethoxymethyl-5,5-diphenylbarbituric acid
DescriptionT-2000 belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Based on a literature review a significant number of articles have been published on T-2000. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,3-dimethoxymethyl-5,5-diphenylbarbituric acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,3-Dimethoxymethyl-5,5-diphenylbarbituric acid 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.
