					 Chemical Properties  | 
				
					 PALE YELLOW LOW MELTING CRYSTALLINE SOLID  | 
			
| 
					 Chemical Properties  | 
				
					 2,6-Dimethylpyrazine has a nutty, coffee-like odor.  | 
			
| 
					 Preparation  | 
				
					 By condensation of 1,2-diaminopropane, followed by column chromatography to separate the 2,6-methylpyrazine from the 2,5-dimethylpyrazine.  | 
			
| 
					 Aroma threshold values  | 
				
					 Detection: 400 to 1500 ppb. Aroma characteristics at 1.0%: musty, cocoa powdery, tobacco, dry leaf tea, earthy mushroom cap and potato-like, meaty, roasted peanut shell, and coffee.  | 
			
| 
					 Taste threshold values  | 
				
					 Taste characteristics at 5.0 ppm: musty and earthy, nutty peanut shell, cocoa powdery, earthy coffee, yeasty, woody, milk roasted peanut.  |
