Common Name | Pyrazineethanethiol |
---|
Description | Pyrazineethanethiol 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 cabbage, meaty, and sulfurous tasting compound. Based on a literature review very few articles have been published on Pyrazineethanethiol. |
