Metabolite Identification
Common Name1,2,4-Triazolo(4,3-b)pyridazine, 7-cyclobutyl-3-(2,6-difluorophenyl)-6-((1-methyl-1H-1,2,4-triazol-5-yl)methoxy)-
Description1,2,4-Triazolo(4,3-b)pyridazine, 7-cyclobutyl-3-(2,6-difluorophenyl)-6-((1-methyl-1H-1,2,4-triazol-5-yl)methoxy)-, also known as MRK-409, belongs to the class of organic compounds known as phenyl-1,2,4-triazoles. These are organic compounds containing a 1,2,4-triazole substituted by a phenyl group. Based on a literature review very few articles have been published on 1,2,4-Triazolo(4,3-b)pyridazine, 7-cyclobutyl-3-(2,6-difluorophenyl)-6-((1-methyl-1H-1,2,4-triazol-5-yl)methoxy)-. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2,4-triazolo(4,3-b)pyridazine, 7-cyclobutyl-3-(2,6-difluorophenyl)-6-((1-methyl-1h-1,2,4-triazol-5-yl)methoxy)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2,4-Triazolo(4,3-b)pyridazine, 7-cyclobutyl-3-(2,6-difluorophenyl)-6-((1-methyl-1H-1,2,4-triazol-5-yl)methoxy)- 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.
