Common Name1-(1-Naphthyl)-2-thiourea
DescriptionN-(naphthalen-1-yl)carbamimidothioic acid, also known as alpha-naphthylthiourea, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Based on a literature review very few articles have been published on N-(naphthalen-1-yl)carbamimidothioic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-(1-naphthyl)-2-thiourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-(1-Naphthyl)-2-thiourea 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.
