Metabolite Identification
Common Name4-Methoxy-2-naphthylamine
Description4-Methoxy-2-naphthylamine belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. 4-Methoxy-2-naphthylamine is a strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-methoxy-2-naphthylamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Methoxy-2-naphthylamine 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.
