Hazard Information | Back Directory | [Description]
2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers)
is like roasted almonds, hazelnuts. This may be prepared from
2-methylchloropyrazine; a mixture of 2-methyl-3-methylthiopyrazine,
2-methyl-5-methylthiopyrazine, and 2-methyl-6-methylthiopyrazine
is obtained. | [Chemical Properties]
2-Methyl-3(or 5 or 6)-methylthiopyrazine has a roasted almond, hazelnut and vegetable aroma. | [Preparation]
From 2-methylchloropyrazine; a mixture of 2-methyl-3-methylthiopyrazine, 2-methyl-5-methylthiopyrazine, and
2-methyl-6-methylthiopyrazine is obtained. | [Aroma threshold values]
Detection: 4 to 60 ppb. Aroma characteristics at 1.0%: toasted popcorn, roasted almond, hazelnut, peanut
and cashewnutty, with a caramellic and corn-chip nuance. | [Taste threshold values]
Taste characteristics at 3 to 10 ppm: nutty, roasted and earthy with coffee and corn nuances, peanut and
pecan nutty, popcorn and corn chip–like with a burnt musty nuance.
