Metabolite Identification
Common Name2,6-Dimethylpyridine
Description2,6-Dimethylpyridine, also known as alpha,alpha'-lutidine or 2,6-lutidine, belongs to the class of organic compounds known as methylpyridines. These are organic compounds containing a pyridine ring substituted at one or more positions by a methyl group. 2,6-Dimethylpyridine 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 2,6-dimethylpyridine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2,6-Dimethylpyridine.
