Metabolite Identification
Common NameMethyl sulfate
Descriptionmethyl sulfate belongs to the class of organic compounds known as sulfuric acid monoesters. These are organic compounds containing the sulfuric acid monoester functional group, with the generic structure ROS(O)(=O)=O, (R=organyl group). methyl sulfate exists in all living organisms, ranging from bacteria to humans. Based on a literature review a significant number of articles have been published on methyl sulfate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methyl sulfate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methyl sulfate 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.
