Chemical Information
FooDB NamePyrazinemethanethiol
DescriptionPyrazinemethanethiol 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. Pyrazinemethanethiol is a meaty and roasted in sugar syrup tasting compound. Based on a literature review very few articles have been published on Pyrazinemethanethiol.
