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.
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
