Chemical Information
FooDB NamePyrazineethanethiol
DescriptionPyrazineethanethiol, also known as fema 3230 or mercaptoethylpyrazine, belongs to the class of organic 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. Pyrazineethanethiol is a moderately basic compound (based on its pKa). Pyrazineethanethiol is a cabbage, meaty, and sulfurous tasting compound.
