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.

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.
