| Common Name | 3-(((4,7-Dichloro-1,3-benzoxazol-2-yl)methyl)amino)-5-ethyl-6-methylpyridin-2(1H)-one |
|---|
| Description | L-697661 belongs to the class of organic compounds known as benzoxazoles. These are organic compounds containing a benzene fused to an oxazole ring Oxazole is five-membered aromatic ring with a nitrogen and an oxygen atoms at the 1- and 3-position, respectively. L-697661 is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-(((4,7-dichloro-1,3-benzoxazol-2-yl)methyl)amino)-5-ethyl-6-methylpyridin-2(1h)-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-(((4,7-Dichloro-1,3-benzoxazol-2-yl)methyl)amino)-5-ethyl-6-methylpyridin-2(1H)-one 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. |
