2-Isopropenyl-3-methylpyrazine

2-Isopropenyl-3-methylpyrazine belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-membered aromatic heterocycle, that includes two nitrogen atoms (at positions 1 and 4) and four carbon atoms. 2-Isopropenyl-3-methylpyrazine is a moderately basic compound (based on its pKa). 2-Isopropenyl-3-methylpyrazine is a methylated derivative of 2-isopropenylpyrazine on which one methyl group has been added at the position C-3 of the benzene ring. 2-Isopropenylpyrazine is a caramel, chocolate, and nutty tasting compound. 2-Isopropenylpyrazine has been detected, but not quantified, in several different foods such as nuts, cereals and cereal products, pulses, cocoa and cocoa products, and tea. Pyrazines and alkylated pyrazines have also been found in the volatile fraction of Cannabis sativa (PMID: 26657499) and are likely a component of marijuana smoke (https://doi.org/10.1007/978-1-59259-947-9_2).
