Chemical Information
FooDB Name5,6,7,8-Tetrahydroquinoxaline
Description5,6,7,8-Tetrahydroquinoxaline 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. 5,6,7,8-Tetrahydroquinoxaline is a bean, cereal, and cheese tasting compound. 5,6,7,8-Tetrahydroquinoxaline has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), cereals and cereal products, breakfast cereal, cocoa and cocoa products, and robusta coffees (Coffea canephora). This could make 5,6,7,8-tetrahydroquinoxaline a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5,6,7,8-Tetrahydroquinoxaline.
