2,3,5-Trimethylpyrazine Usage And Synthesis
Chemical Properties | CLEAR YELLOW LIQUID |
Chemical Properties | 2,3,5-Trimethylpyrazine has a baked potato or roasted nut aroma. |
Preparation | From 2,5-dimethylpyrazine by ring alkylation with MeLi; by condensing propylenediamine with 2,3-butanedione. |
Aroma threshold values | Detection: 400 ppb to 9 ppm (9 ppm in water) |
Taste threshold values | Taste characteristics at 80 ppm: raw, musty, nutty and potato. |
Safety Profile | Moderately toxic by ingestion. Combustible liquid. When heated to decomposition emits toxic fumes of NOx. |
