Chemical Information
FooDB Name2-Acetyl-3,5-dimethylpyrazine
Description2-Acetyl-3,5-dimethylpyrazine belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. 2-Acetyl-3,5-dimethylpyrazine is a caramel, hazelnut, and nutty tasting compound. 2-Acetyl-3,5-dimethylpyrazine has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 2-acetyl-3,5-dimethylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Acetyl-3,5-dimethylpyrazine.
