Metabolite Identification

Common Name

6-Methylquinoline

Description

6-Methylquinoline belongs to the class of organic compounds known as quinolines and derivatives. Quinolines and derivatives are compounds containing a quinoline moiety, which consists of a benzene ring fused to a pyrimidine ring to form benzo[b]azabenzene. 6-Methylquinoline is a castoreum, civet, and fecal tasting compound. 6-Methylquinoline has been detected, but not quantified in, several different foods, such as black tea, green tea, herbal tea, red tea, and teas (Camellia sinensis). This could make 6-methylquinoline a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 6-Methylquinoline.
