Chemical Information
FooDB Name2-Ethyl-5-methylpyrazine, 9CI, 8CI
Description2-Ethyl-5-methylpyrazine, 9CI, 8CI, also known as 2,5-methylethylpyrazine or fema 3154, belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-member aromatic heterocycle, that consists of two nitrogen atoms (at positions 1 and 4) and four carbon atoms. 2-Ethyl-5-methylpyrazine, 9CI, 8CI is a sweet and fruit tasting compound. 2-Ethyl-5-methylpyrazine, 9CI, 8CI 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-ethyl-5-methylpyrazine, 9ci, 8CI a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Ethyl-5-methylpyrazine, 9CI, 8CI.
