| | 2,3-Dimethylpyrazine Usage And Synthesis |
| Chemical Properties | CLEAR YELLOW TO ORANGE LIQUID | | Chemical Properties | 2,3-Dimethylpyrazine has a nutty, cocoa-like odor and green note. | | Uses | flavors and fragrances | | Definition | ChEBI: 2,3-Dimethylpyrazine is a member of pyrazines. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 28, p. 1703, 1963 DOI: 10.1021/jo01041a506 | | General Description | The bacterium strain DP-45, identified as Rhodococcus erythropolis, was grown on 2,3-dimethylpyrazine. | | Safety Profile | Moderately toxic by
ingestion and intraperitoneal routes.
Flammable liquid when exposed to heat,
sparks, or flame. When heated to
decomposition it emits toxic fumes of NOx |
