Metabolite Identification
Common NameSulfamethoxypyridazine
DescriptionSulfamethoxypyridazine, also known as sulphametoxipiridazina or lederkyn, belongs to the class of organic compounds known as aminobenzenesulfonamides. These are organic compounds containing a benzenesulfonamide moiety with an amine group attached to the benzene ring. Based on a literature review a significant number of articles have been published on Sulfamethoxypyridazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Sulfamethoxypyridazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Sulfamethoxypyridazine 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.
