Description6-[(4-chlorophenyl)methyl]-2H,3H,5H,6H,7H-[1,3]thiazolo[3,2-a]pyrimidine-5,7-dione belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Based on a literature review very few articles have been published on 6-[(4-chlorophenyl)methyl]-2H,3H,5H,6H,7H-[1,3]thiazolo[3,2-a]pyrimidine-5,7-dione. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nuclomedone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nuclomedone 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.
