| Hazard Information | Back Directory | [Chemical Properties]
2-Methoxy-3(5 and 6)-isopropylpyrazine has an earthy, bell pepper, raw potato, galbanum aroma. | [Occurrence]
Reported found in asparagus, cabbage, peas, carrot, cucumber, lettuce, onion, potato, bell pepper, tomato,
ginger, white wine, coffee, peanut, beans, beetroot, parsnip root and dill herb. | [Uses]
flavors and fragrances | [Preparation]
(a) From 2-hydroxy-3-propylpyrazine by ethylation with diazomethane; the 2-hydroxy-3-propylpyrazine is pre pared by condensing norvaline amide hydrochloride with glyxoal (a + b + c). A mixture can be obtained by methoxylation of
isopropylchloropyrazine. | [Aroma threshold values]
Detection: 0.002 to 10 ppb. |
