Metabolite Identification
Common Name2-Methylbenzothiazole
Description2-Methylbenzothiazole belongs to the class of organic compounds known as benzothiazoles. These are organic compounds containing a benzene fused to a thiazole ring (a five-membered ring with four carbon atoms, one nitrogen atom and one sulfur atom). 2-Methylbenzothiazole 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 2-methylbenzothiazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methylbenzothiazole.
