<p>Quinoxalines are a class of heterocyclic compounds that is structurally related to the more common amino acid, tryptophan. They are typically synthesized by modifications of the quinoxaline ring system with epoxide, amine, or carbonyl groups. Quinoxalines can be analyzed using many different techniques including gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and nuclear magnetic resonance spectroscopy. The most common modification is the addition of an aminoguanidine group that is used to distinguish between 2-ethyl-3-methylquinoxaline and 3-ethyl-2-methylquinoxaline. The reaction time between glyoxal and aniline to produce 2-ethyl-3-methylquinoxaline can be optimized by adding potassium dichromate as a catalyst.</p>
