Common Name

4-Methyl-3-[4-(4-oxopyridin-1-yl)phenyl]-4,5-dihydro-1H-pyridazin-6-one

Description

4-Methyl-3-[4-(4-oxopyridin-1-yl)phenyl]-4,5-dihydro-1H-pyridazin-6-one, also known as SK and F-95654, belongs to the class of organic compounds known as pyridazinones. Pyridazinones are compounds containing a pyridazine ring which bears a ketone. Based on a literature review very few articles have been published on 4-Methyl-3-[4-(4-oxopyridin-1-yl)phenyl]-4,5-dihydro-1H-pyridazin-6-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-methyl-3-[4-(4-oxopyridin-1-yl)phenyl]-4,5-dihydro-1h-pyridazin-6-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Methyl-3-[4-(4-oxopyridin-1-yl)phenyl]-4,5-dihydro-1H-pyridazin-6-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.
