Common Name6-Methyl-N-(2H-tetrazol-5-yl)pyridine-2-carboxamide
Description6-Methyl-N-(2H-tetrazol-5-yl)pyridine-2-carboxamide belongs to the class of organic compounds known as pyridinecarboxamides. Pyridinecarboxamides are compounds containing a pyridine ring bearing a carboxamide. Based on a literature review very few articles have been published on 6-Methyl-N-(2H-tetrazol-5-yl)pyridine-2-carboxamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 6-methyl-n-(2h-tetrazol-5-yl)pyridine-2-carboxamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 6-Methyl-N-(2H-tetrazol-5-yl)pyridine-2-carboxamide 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.
