2,5-Dimethyl-6-vinylpyrazine
2,5-dimethyl-6-vinylpyrazine is a member of the class of 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. 2,5-dimethyl-6-vinylpyrazine is soluble (in water) and a moderately basic compound (based on its pKa). 2,5-dimethyl-6-vinylpyrazine can be found in kohlrabi, which makes 2,5-dimethyl-6-vinylpyrazine a potential biomarker for the consumption of this food product.
