Chemical Information
FooDB Name1-Methylnaphthalene
Description1-Methylnaphthalene, also known as fema 3193, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. 1-Methylnaphthalene is possibly neutral. 1-Methylnaphthalene is a camphor, chemical, and medicinal tasting compound. 1-Methylnaphthalene is found, on average, in the highest concentration within black walnuts. 1-Methylnaphthalene has also been detected, but not quantified in, asian pears and corns. This could make 1-methylnaphthalene a potential biomarker for the consumption of these foods. 1-Methylnaphthalene is a potentially toxic compound.
