2,5-Dimethyl pyrazine Usage And Synthesis
Chemical Properties clear colorless to pale yellow liquid
Chemical Properties 2,5-Dimethylpyrazine has a characteristic odor of earthy, potato-like odor.
Occurrence Reported to be present in bakery products, roasted barley, cocoa products, roasted coffee, dairy products, pork, peanuts, pecans, filberts, popcorn, potato products, rum and whiskey, soy products; a volatile component in roasted filberts and in potato chips; reportedly identified in the fat of cooked beef; also reported found in toasted off-flavors. Also reported in cheeses, butter, boiled eggs, grilled beef, tea, barley, oats, oatmeal, soybeans, heated beans, kohlrabi, shrimp and mushrooms. Also reported found in coffee, potato chips and shrimp
Uses 2,5-Dimethyl pyrazine is used for blending food, nuts and beverage flavors.
Preparation By the interaction of acrolein and ammonia when heated in glycerol in the presence of ammonium salts; by self-condensation of aminoacetone, followed by oxidation with mercury chloride.
Aroma threshold values Detection: 80 ppb to 1.8 ppm
Taste threshold values Taste characteristics at 7.5 ppm: musty, potato, cocoa and nutty with a fatty and oily nuance
Safety Profile Moderately toxic by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx
Purification Methods Purify it via its picrate (m 150o) which is decomposed with a base (e,g, KOH) and distilled. [Wiggins and Wise J Chem Soc 4780 1956]. [Beilstein 23/5 V 403.]
