Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C 4 H 4 N 2. It is a symmetrical molecule with point group D 2h. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. It is a "deliquescent crystal or wax-like solid with a pungent, sweet, corn-like, nutty odour". [3]
2,6-Dimethylpyrazine is also used as flavor additive and odorant in foods such as cereals [6] and products such as cigarettes. It occurs naturally in baked potato, black or green tea, crispbread, French fries, malt, peated malt, raw asparagus, roasted barley, roasted filberts or pecans, squid, wheat bread, wild rice (Zizania aquatica), and wort.

2-Acetylpyridine is an organic compound with the formula CH 3 COC 5 H 4 N. It is a viscous colorless liquid that is widely used as a flavoring substance. It is found in malt and produced by the Maillard reaction and by nixtamalization. It contributes to the flavor of corn tortillas, popcorn, and beer. [3]
3-Isobutyl-2-methoxypyrazine (2-isobutyl-3-methoxypyrazine [1] also known as Grindstaff pyrazine) is a methoxypyrazine that is very similar to isopropyl methoxy pyrazine except that the alkyl side-group contains an isobutyl group attached to the carbon alpha to the methoxy sidegroup instead of an isopropyl side-group at that same carbon position.
2,6-Diacetylpyridine is an organic compound with the formula C 5 H 3 N(C(O)CH 3) 2. It is a white solid that is soluble in organic solvents. It is a disubstituted pyridine. It is a precursor to ligands in coordination chemistry. [1] [2]
From January 2008 to December 2012, if you bought shares in companies when Bradley Sheares joined the board, and sold them when he left, you would have a 3.2 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
In an observational study, tetramethylpyrazine was the dominant volatile organic compound in one sourdough starter. [2] When purified, tetramethylpyrazine is a colorless solid. It is classified as an alkylpyrazine. Its biosynthesis involves amination of acetoin, the latter derived from pyruvate. [3]
