描述
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. Vinylpyrazine is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Vinylpyrazine is a nutty tasting compound found in kohlrabi, which makes vinylpyrazine a potential biomarker for the consumption of this food product.
